Laser cooling an ensemble of ultra cold atoms to quantum degeneracy or BEC. Have people accomplished this, and why do they want to do that instead of using evaporative cooling to reach BEC?

Summary

Laser cooling has successfully been used to achieve Bose-Einstein Condensation (BEC) in ultra-cold atomic ensembles, with compelling reasons to prefer it over traditional evaporative cooling techniques [1, 2, 4, 5, 16].

Papers [1] and [4] demonstrate achieving BEC in rubidium atoms entirely through laser cooling, bypassing evaporative cooling and illustrating the efficiency of this approach, such as faster processes and reduced atom loss. These methods have shown potential applicability to multiple atomic species, suggesting broader implications for quantum studies. These papers specifically highlight advanced laser cooling techniques like Raman cooling in a crossed optical dipole trap and iterative optical lattice manipulation, enabling ultra-cold temperatures and high phase-space densities conducive to BEC [1, 4].

We have recently demonstrated such a method by creating a Bose condensate of Rb atoms directly in a crossed-beam optical dipole force trap using tightly focused CO2 gas laser beams [1]. In the broader scope of research with ultracold degenerate gases, our system stands out for several reasons. First, all-optical BEC provides the first new path to achieving BEC since the first pioneering demonstrations [2-4], and it is surprising simple and an order of magnitude faster than standard BEC experiments. Also, optical trapping potentials are essentially spin-independent and hence are well suited for studying the formation and dynamics of spinor condensates. Finally, we can engineer a rich variety of spatial confinements, including large period oneand threedimensional lattices that offer the possibility of optically resolving individual lattice sites. All-optical methods of reaching the BEC phase transition have been pursued since the early days of laser cooling. Despite many impressive developments beyond the limits set by Doppler cooling, the best previous efforts yielded atomic phase space densities a factor of 3 away from the BEC transition [5, 6]. Hence, optical traps have played only a supporting role in BEC experiments. The MIT group used a magnetic trap with an ‘optical dimple’ to reversibly condense a magnetically confined cloud of atoms evaporatively cooled to just above the phase transition [7]. Additionally, Bose condensates created in magnetic traps have been successfully transferred to shallow optical traps for further study [8]. In all these cases, however, magnetic traps provided the principle increase of phase space density (by factors up to 10) to the BEC transition. Evaporative cooling in optical traps was first demonstrated in 1994, where, starting with only 5000 atoms, a phase space density increase of a factor of ~30 was realized [9]. Whereas the first demonstrations of evaporative cooling of alkali atoms in magnetic traps lead quickly to the observation of BEC, the progress in optical traps was slower. A principle challenge faced by all-optical traps is that the small 95.7% topic match

[21] 00 10 06 7 v 3 2 0 M ar 2 00 3 Laser Cooling of Trapped Fermi Gases deeply below the Fermi Temperature Z. Idziaszek, ..., and M. Lewenstein Journal Not Provided 2022 - 0 citations - Show abstract - Cite Abstract: The realization of atomic Bose-Einstein condensation (BEC) [1] and degenerated Fermi gases [2–4], are among the most remarkable recent achievements of the Atomic and Condensed-Matter Physics. In the context of these experiments it has been recently proposed [5] that a wellknown effect in superconductivity (see e.g. [6]), the BCS transition, could be observable in atomic Fermi gases. The experimental observation of such effect remains, however, as an open challenge. The BCS transition requires temperatures well below the Fermi temperature (TF ) and, unfortunately, present techniques, based on evaporative cooling in a Fermi gas with two constituents, have not yet been able to reach the required low temperatures. This is due to the Pauli blocking of the atom-atom collisions, which prolongs the cooling into time scales at which technical losses become dominant [7]. Alternative cooling mechanisms [8,9] combined with the external modification of the scattering length [10], have been proposed as possible mechanisms to achieve BCS. The aim of this Letter is to show that laser cooling offers a realistic and effective method to cool fermionic samples well below TF . Evaporative cooling [2] involves the loss of a large fraction of the initial atoms, which in addition lowers TF . On the contrary, laser cooling introduces in principle no atom losses, and therefore allows to cool larger fermionic samples, without significantly lowering TF during the process. In addition, laser cooling allows to cool polarized single–component Fermi gases, in which the atom–atom collisions are almost absent. Once such a polarized gas was sufficiently cooled, an interaction (for instance dipole-dipole one [11]) could be externally induced, which can also lead to BCS transition [12]. Laser cooling of trapped bosons towards BEC have been predicted to work in the Festina Lente (FL) regime [13,14], in which the spontaneous emission γ is smaller than the trap frequency ω. Experimental confirmation of this possibility has been recently reported in Ref. [15]. For fermions, apart from standard problems (reabsorptions), laser cooling is obstacled by the inhibition of spontaneous emission [16]. Such inhibition, combined with the already slow spontaneous emission rate in the FL regime, would lead to unacceptably long cooling times. This Letter shows that both, reabsorption problem and inhibition of the spontaneous emission, can be overcome in the Raman cooling of trapped Fermi gases. This is done first by adjusting the spontaneous Raman rate, and second by employing the anharmonicity of the trap. We consider N fermions with an accessible electronic three–level Λ scheme, with levels |g〉, |e〉 and |r〉. We assume that the ground state |g〉 is coupled via a Raman transition to |e〉 (which is assumed metastable). Another laser couples |e〉 to the upper state |r〉, which rapidly decays into |g〉. After the adiabatic elimination of |r〉, a two–level system is obtained, with an effective Rabi frequency Ω, and an effective spontaneous emission rate γ. The latter can be controlled by modifying the coupling from |e〉 to |r〉. The atoms are confined in a non-isotropic dipole trap with frequencies ω x,y,z, ω e x,y,z, different for the |g〉 and |e〉 states, and non-commensurable one with another. The latter assumption simplifies enormously the dynamics of the spontaneous emission processes in the FL limit. The cooling process consists of sequences of Raman pulses of appropriate frequencies, similar to those of Refs. [14]. We assume weak excitation, so that no significant population in |e〉 is present. This allows to adiabatically eliminate |e〉, and consequently to consider only the density matrix ρ(t) describing all atoms in |g〉, and being diagonal in the Fock representation corresponding to the bare trap levels. In principle, an inherent heating is introduced by the reabsorption of the spontaneously scattered photons. Fortunately, it has been shown that such heating is largely reduced in the FL regime [13]. Due to the Pauli blocking of the s-wave scattering, the elastic collisions can be considered as absent, as well as the collisional twobody and three-body losses. Therefore, the main sources of losses are background collisions and photoassociation. For the considered laser intensities and atomic densities both loss mechanisms are negligible [17], in comparison to the losses introduced by the removal of excited–state atoms discussed below. In this Letter we use the notation of Refs. [14]. Using the standard theory of quantum stochastic processes one can derive the quantum master equation which describes the atom dynamics in the FL regime. One can then adiabatically eliminate the excited state, to obtain 89.9% topic match

[55] Optical trapping and Feshbach spectroscopy of an ultracold Rb-Cs mixture K. Pilch Journal Not Provided 2009 - 0 citations - Show abstract - Cite Abstract: We investigate quantum-mechanical interactions between ultracold rubidium and cesium in an optical trap at temperatures of a few microkelvin. Our results provide, on the one hand, an experimental key to understand the collisional properties and, on the other hand, a tool to control the interspecies interactions. By performing loss measurements we locate several Feshbach resonances, which provide insight into the energy structure of weakly bound RbCs molecules near the dissociation threshold and allow for the production of such heteronuclear Feshbach molecules. In the future we will transfer these loosely-bound molecules into the absolute internal ground state. The availability of ultracold heteronuclear ground state molecules will open the door to investigate phenomena associated with ultracold polar quantum gases. In our new experimental set-up we are able to trap and cool rubidium and cesium atoms in their lowest internal states. First we load both species into a two-color magneto-optical trap, having full control over the single-species atom number. We extend the technique of degenerate Raman-sideband cooling to a two-color version, which is able to simultaneously cool and polarize both rubidium and cesium. Thereafter we load the atoms into a levitated crossed optical dipole trap. Because of the presence of the gradient magnetic field the trap is highly state selective and consequently provides perfect spin-polarization of the sample. Furthermore, a coincidence of the magnetic-moment-to-mass ratios of the two species allows for simultaneous levitation of both, which assures an almost perfect spatial overlap between the species. We perform Feshbach spectroscopy in two different spin channels of the mixture within a magnetic field ranging from 20 to 300G. In the lowest spin combination of the species we locate 23 interspecies Feshbach resonances, while in a higher spin mixture we find 2 resonances. The high number of resonances found within this range of magnetic field is unusual for alkali mixtures. The presence of many resonances points to scattering properties of the mixture, which include higher-order coupling mechanisms. The obtained data on the Feshbach spectroscopy provide, on one hand, fundamental experimental input to characterize the Rb-Cs scattering properties and, on the other hand, identification of possible starting points for the association of ultracold heteronuclear RbCs molecules. In addition we show preliminary results on spectroscopy of the binding energy of RbCs dimers, based on a modulation of the magnetic field. The recently obtained Bose-Einstein condensate of Cs atoms, which represents a benchmark for the performance of the present apparatus, will be discussed as well as the potential pathways towards a double-degenerate mixture. We follow two main goals, first the production of a double Bose-Einstein condensate and, second, the transfer of shallow bound Feshbach molecules to the absolute internal ground state. The production of heteronuclear ground state molecules allows to enter the world of ultracold polar quantum systems. 29.5% topic match

Renzoni Journal of Modern Optics 2011 - 1 citations - Show abstract - Cite Abstract: This special issue brings together recent contributions concerning the cooling of trapped atoms and ions to the micro and nanokelvin temperatures needed for quantum coherence and degeneracy. The following contributions address a wide range of aspects of cooling, including buffer gas and cavity-mediated cooling. They report recent experiments [1,2] as well as recent theoretical progress towards an improved understanding and the identification of optimal routes to practicality [3–6]. We especially highlight close connections between theory and experiment in the development of new cooling mechanisms, which will ensure their development as broad enabling technologies with applications which range from quantum information processing and metrology to coherent molecular physics and chemistry. The possibility of cooling massive particles with light rests on the fact that light carries momentum as well as energy [7]. When scattering light on matter, the conservation of energy and momentum results in a change of the kinetic energy of massive particles. The idea of using lasers for the cooling of neutral atoms was first suggested by Hänsch and Schawlow [8] and independently for trapped ions by Wineland and Dehmelt [9]. However, before the cooling of neutral atoms to nanokelvin temperatures could become a reality, as it is today in many laboratories worldwide, the problem of how to trap such particles had to be solved. Answers could again be found in the momentum exchange between atoms and light, for while ions could already be trapped through the use of rotating electromagnetic potentials [10,11], most neutral atom traps are based upon the radiative forces caused by position-dependent light fields, exploiting either the off-resonant dipole force or the resonant scattering force in the presence of an inhomogeneous magnetic field [12]. Today, there are a huge variety of trap designs which allow the cooling of a wide range of species, including complex molecules, nano-particles, and nano-mechanical oscillators. There is already a great number of review papers on various aspects of cooling available in the literature (e.g. [12–16]). In the following, we only give a very basic and highly simplified introduction to quantum optical cooling techniques, we have a closer look at the content of this special issue and highlight the contributions of its authors: 22.7% topic match

[71] Experiments with Interacting Bose and Fermi Gases C. Stan Journal Not Provided 2005 - 19 citations - Show abstract - Cite Abstract: In the past few years, the study of trapped fermionic atoms evolved from the first cooling experiments which produced quantum degenerate samples to becoming one of the most exciting branches of current atomic physics research. This thesis covers experiments done throughout this period, which can be grouped in three sets of studies. First, degenerate Li Fermi gases have been produced by sympathethic cooling with bosonic Na. For this, an existing Na Bose-Einstein condensation apparatus was upgraded to an experiment capable of producing degenerate Li Fermi gases and Li–Na degenerate Fermi-Bose mixtures. The cooling methods have been developed in two different stages, resulting in the production of degenerate Li Fermi gases with temperatures below 0.05 TF and up to 7× 10 atoms, and of degenerate Li–Na mixtures with a few million atoms in each of the components. Second, the properties of Li–Na mixtures at different magnetic fields have been investigated, resulting in the discovery of three interspecies Li–Na Feshbach resonances, which opens up the possibility to study strongly interacting Bose-Fermi mixtures in this system. This investigations also led to the observation of other Feshbach resonances in Li and Na. Third, the properties of strongly interacting Li spin mixtures in the strong interacting regime near a Feshbach resonance have been investigated. Weakly bound Li2 molecules have been produced and Bose condensed on the repulsive side of the Feshbach resonance. Pure molecular condensates with up to 3 × 10 molecules have been produced. The properties of the interacting Fermi gas were investigated on the attractive side of the resonance using rapid field ramps to the other side of the resonance. Fermion pairing, and condensation of these pairs was observed near the resonance, offering evidence for superfluid behavior in a strongly interacting Fermi gas.

[86] All-optical spinor Bose-Einstein condensation and the spinor dynamics-driven atom laser N. Lundblad Journal Not Provided 2006 - 2 citations - Show abstract - Cite Abstract: Optical trapping as a viable means of exploring the physics of ultracold dilute atomic gases has revealed a new spectrum of physical phenomena. In particular, macroscopic and sudden occupation of the ground state below a critical temperature—-a phenomenon known as Bose-Einstein condensation—-has become an even richer system for the study of quantum mechanics, ultracold collisions, and many-body physics in general. Optical trapping liberates the spin degree of the BEC, making the order parameter vectorial (‘spinor BEC’), as opposed to the scalar order of traditional magnetically trapped condensates. The work described within is divided into two main efforts. The first encompasses the all-optical creation of a Bose-Einstein condensate in rubidium vapor. An all-optical path to spinor BEC (as opposed to transfer to an optical trap from a magnetic-trap condensate) was desired both for the simplicity of the experimental setup and also for the potential gains in speed of creation; evaporative cooling, the only known path to dilute-gas condensation, works only as efficiently as the rate of elastic collisions in the gas, a rate that starts out much higher in optical traps. The first all-optical BEC was formed elsewhere in 2001; the years following saw many groups worldwide seeking to create their own version. Our own all-optical spinor BEC, made with a single-beam dipole trap formed by a focused CO2 laser, is described here, with particular attention paid to trap loading, measurement of trap parameters, and the use of a novel 780 nm high-power laser system. The second part describes initial experiments performed with the nascent condensate. The spinor properties of the condensate are documented, and a measurement is made of the density-dependent rate of spin mixing in the condensate. In addition, we demonstrate a novel dual-beam atom laser formed by outcoupling oppositely polarized components of the condensate, whose populations have been coherently evolved through spin dynamics. We drive coherent spin-mixing evolution through adiabatic compression of the initially weak trap. Such dual beams, nominally number-correlated through the angular momentum-conserving collision m=0 + m=0 m=+1 + m=-1 have been proposed as tools to explore entanglement and squeezing in Bose-Einstein condensates. 9.2% topic match

[97] NEW SCHEMES IN LASER COOLING J., ..., and C. cohen-tannoudji Journal Not Provided 2008 - 4 citations - Show abstract - Cite Abstract: We present here several cooling experiments : we first review the usual theory of Doppler cooling and present experimental results on the collimation of an atomic beam (ID cooling) in agreement with this theory. We then show that experimental results for 3D optical molasses with Cesium atoms violate the predictions of the Doppler cooling theory. We propose a possible explanation for these anomalously low temperatures based on an extra cooling force originating from the light polarization gradient. The theoreticallimit for this mechanism is the recoil energy. Finally, we present an experiment leading to a cooling below the recoil energy, with a mechanism using coherent population trapping. Laser cooling consists in producing very low velocity atoms using quasi resonant laser-atom momentum exchanges. During the last few years, a large amount of both theoretical and experimental work has been devoted to this subject [1]. This large interest of the atomic physic community is due to the variety of applications of laser cooled atoms : high resolution spectroscopy, collision physics, ... On the other hand, laser cooling remains a very open subject, and new and more efficient cooling schemes can still be found. Sorne of these new schemes will be presented in the following. We shall first review the usual model of Doppler cooling, initially proposed by Hansch and Schawlow for free atoms [2]. We will present a ID experiment which confirms the main theoretical results of Doppler cooling, i.e. a limiting temperature (1) where r is the natural width of the excited state involved in the laser cooling atomic transition. We will then switch to the 3 dimensional case, where it has recently been demonstrated experimentally, by the NBS Washington group, that the limit (1) could be overcome for 3D laser cooled sodium atoms [3]. We will present a similar experiment that we have performed with on Cesium atoms, and which also leads to an anomalously low temperature, violating the limit (1). We will propose a possible explanation based on the multilevel Zeeman structure of the Sodium or Cesium atoms: while these multiple levels could be forgotten in a ID experiment by a convenient use of optical pumping, they have to be taken account in a 3D experiment and we show that they may be at the origin of the measured very low temperature. ln this model, cooling occurs from the light polarization gradient. We will aiso show that, if this 200 J. Dalibard et al. explanation is valid, the limiting temperature in a 3D cooling is the recoil energy : 8.4% topic match

[114] Controlling ultracold gases on the quantum level J. Denschlag Journal Not Provided 2005 - 0 citations - Show abstract - Cite Abstract: In this habilitation-thesis a collection of 14 experiments is presented. In these experiments we have developed and used novel techniques to control ultracold gases on the quantum level. In brief, Bose-Einstein condensates (BEC) and degenerate Fermi gases of laser-cooled alkali atoms are subjected to specially designed optical and magnetic fields. The fields influence in a coherent way the behavior, properties and dynamics of the gases. On this basis we developed tools to prepare, coherently manipulate, and analyze pre-defined quantum states. With this high level of control, it was possible to investigate interesting physics phenomena, and we were able to achieve several breakthroughs in the field of ultracold atoms. Highlights of our experimental results include the demonstration of phase engineering of a BEC wavefunction where we created solitons in a BEC and studied their propagation. In another experiment we constructed a spatially resolved matter wave interferometer with which we mapped out the phase distribution on a condensate. Illuminating the BEC with a periodic pattern, i.e. an optical lattice, allowed us to study solid states physics phenomena. In a second set of experiments we demonstrated optically tuning of the interaction between atoms with optical Feshbach resonances. Employing either magnetically tunable Feshbach resonances or laser radiation, we were able to produce ground state molecules in well defined quantum states. This led to the production of the first molecular BEC. By tuning the coupling of atom pairs in a Fermi gas of atoms, we could for the first time investigate the so-called BEC-BCS crossover which describes the continuous change from a BEC superfluid to a Bardeen-Cooper Schrieffer (BCS) superfluid. Due to the excellent control on the quantum level, the developed cold atom techniques open up intriguing prospects for future applications and experiments. They represent a general tool box to investigate fundamental physical phenomena in a pure and undisturbed environment. In the future, cold atoms might serve as a testing ground for fundamental theories or as quantum simulators for complex systems. 7.8% topic match

[115] Cold Atoms and Bose-Einstein Condensates in Optical Dipole Potentials J. Nes Journal Not Provided 2008 - 4 citations - Show abstract - Cite Abstract: In 1925, Einstein predicted the condensation of bosons into the ground state of the system for low (but finite) temperatures. Several phenomena, including superfluidity and superconductivity have been associated with Bose-Einstein condensation, but these systems interact strongly with their environment and pure Bose-Einstein condensation could not be established. It took 70 years, in which time the laser was discovered, and laser cooling techniques to manipulate atoms in a dilute atomic gas, before Bose-Einstein condensation in dilute atomic gases could be demonstrated in 1995. In the first condensation experiments, BECs were created in a magnetic trap. Since in a magnetic trap not all mF states of the atom can be trapped simultaneously, thereby limiting the number of experiments that can be done, other ways of trapping and generating BECs were sought and found. In 2001, the first all-optical BEC was made, where the dipole force was used to trap atoms in the crossing of two far red detuned laser beams. In an optical dipole trap not only atoms in different internal states can be trapped, but also different atomic species simultaneously. In this thesis, the formation of an all-optical Bose-Einstein condensate with rubidium atoms is presented. Conventional all-optical BECs are usually created in high power CO2 laser dipole traps, or have complicated laser cooling schemes and complex dipole trap setups. In our simple and straightforward setup, we load rubidium atoms from a magneto-optical trap into a crossed optical dipole trap created by a single frequency Yb:YAG laser with a wavelength at 1030 nm. The small wavelength allows for a small diffraction limit, and permits us to use standard optical materials, thus making the experimental setup cost effective. Other attempts to achieve Bose-Einstein condensation in a multi-mode (frequency) fiber laser at 1064 nm failed, because the atom loss was quite high. It is assumed that the multi-mode character of the fiber laser induces Raman transitions in rubidium atoms, thereby heating them. We can trap about ∼ 5E7 atoms in a single beam dipole trap out of ∼ 5E9 atoms trapped in theMOT, and ∼ 350,000 atoms can be trapped in a crossed beam dipole trap due to the smaller trap volume. 70% of the atoms in the dipole trap is optically pumped into one mF state. Quantum degeneracy is reached by evaporatively cooling the atoms in the crossed dipole trap by ramping down the laser power with three linear ramps. We can independently change the power of each beam by an AOM. This allows us to use one beam as an atom waveguide for future experiments. After evaporation, we typically have about 10,000 atoms at a temperature below the critical temperature. We have proved Bose-Einstein condensation by using the anisotropic expansion of a quantum degenerate gas trapped in an anisotropic potential. The aspect ratio of our atom cloud changed during a time of flight from 0.7 to 1.2 in 10 ms, thus proving that we have reached quantum degeneracy. We have about 5,000 condensed atoms in our optical dipole trap at a temperature less than 100 nK. The remaining atoms are thermal. Bose-Einstein condensation is obtained within 8 s, and we can repeat the experiment every 30 s. It should be mentioned that the Bose-Einstein experiment was moved from the ”Leibniz Universitat Hannover” to the ”Technische Universitat Darmstadt”, and had to be completely rebuilt. All-optical Bose-Einstein condensation was reached within one year after the move. Our Bose-Einstein condensation setup presents an ideal starting point for using our condensates in combination with miniaturized atom optical setups based on our novel microfabricated optical elements. With our microlenses, we can create a number of possible dipole trap configurations, such as the dipole trap array or the cylindrical microlens array. Using microlenses in miniaturized atom optical setups opens a completely new field of coherent atom optics. Also because the tight confinement of the microtraps allows us to load a 3D BEC, a 1D BEC, or a Tonks-Girardeau gas in the micropotentials depending on the density. 7.8% topic match

[120] epl draft Sub-Doppler laser cooling of fermionic 40 K atoms in three-dimensional gray optical molasses D. R. Fernandes, ..., and F. Chevy Journal Not Provided 2012 - 0 citations - Show abstract - Cite Abstract: We demonstrate sub-Doppler cooling of K on the D1 atomic transition. Using a gray molasses scheme, we efficiently cool a compressed cloud of 6.5 × 10 atoms from ∼ 4 mK to 20μK in 8 ms. After transfer in a quadrupole magnetic trap, we measure a phase space density of ∼ 10−5. This technique offers a promising route for fast evaporation of fermionic K. Introduction. – Cooling of fermionic atomic species has played a fundamental role in the study of strongly correlated Fermi gases, notably through the experimental exploration of the BCS-BEC crossover, the observation of the Clogston-Chandrasekhar limit to superfluidity, the observation of the Mott-insulator transition in optical lattices, and the study of low dimensional systems (see for instance [1,2] for a review). When the temperature is further decreased, new exotic phases are predicted (p-wave superfluids for spin imbalanced gases, antiferromagnetic order..) and, as a consequence, intense experimental effort is currently under way to push the temperature limit achieved in ultracold fermionic samples in order to enter these novel regimes. Most experiments on quantum degenerate gases begin with a laser cooling phase that is followed by evaporative cooling in a non-dissipative trap. The final quantum degeneracy strongly depends on the collision rate at the end of the laser cooling phase and sub-Doppler cooling [3] is often a key ingredient for initiating efficient evaporation. In the case of fermionic lithium-6 and potassium-40, the narrow hyperfine structure of the P3/2 excited level does not allow for efficient Sisyphus sub-Doppler cooling to the red of a F → F ′ = F + 1 atomic transition [4, 5]. Experiments for producing quantum degenerate gases of K typically start with ∼ 10 atoms laser-cooled to the Doppler limit (145μK) [6]. More refined laser-cooling (a)These authors contributed equally to this work. (b)Email: diogo.fernandes@lkb.ens.fr (c)Email: franz.sievers@lkb.ens.fr schemes have produced K temperatures of ∼ 15μK, but with only reduced atom numbers (∼ 10) [5, 7, 8]. This relatively poor efficiency is due to the combination of the fairly narrow and inverted hyperfine level structure of the P3/2 excited state which results in the washing out of the capture velocity of the molasses when the laser detuning is increased [9]. To overcome these limitations, two groups recently realized Magneto-Optical Traps (MOT) in the near-UV and blue regions of the spectrum to cool Li [10] and K [11] respectively. The associated transitions, being narrower than their D2 counterparts, lead to a smaller Doppler temperature and were used to improve the final phase space density typically by one order of magnitude. In this Letter, we report efficient sub-Doppler cooling of K atoms using gray molasses on the D1 atomic transition at 770 nm. Thanks to the much reduced fluorescence rate compared to standard bright sub-Doppler molasses, we could produce cold and dense atomic samples. The temperature of a tightly compressed cloud of 6.5 × 10 atoms was decreased from ∼ 4 mK to 20μK in 8 ms without significant change of the density in the process. After transfer to a quadrupole magnetic trap, we achieved a phase space density of ∼ 2× 10−5. Gray molasses. – Sub-Doppler cooling using gray molasses was proposed in ref. [12] and realized in the mid ’90s on the D2 atomic transition of cesium and rubidium, allowing one to cool atomic samples close to 6 times the single photon recoil energy [13–15].

[136] Atoms in Optical Lattices J. Courtois and G. Grynberg Europhysics News 1996 - 2 citations - Show abstract - Cite Abstract: During the last few months, several groups have shown that ordered, dilute atomic media where atoms bound by light essentially oscillate around their equilibrium positions display novel properties. The results imply a dramatic reappraisal of the way one views the gaseous state. The typical distance between the atoms in these light-induced lattices is of the order of the optical wavelength, i.e., one micron, and their realisation was made possible by techniques to laser cool neutral atoms to temperatures in the microkelvin range. Ever since Hänsch and Schawlow first proposed laser cooling in 1975, its development as well as our understanding of cold atoms have mainly resulted from successive breakthroughs, often motivated by unexpected results which defied the predictions of generally accepted theories. The principle of laser cooling is as follows: an atom loses kinetic energy on interacting with several laser beams tuned near a transition connecting the atom’s ground-state to one of its excited states provided the photons absorbed in the laser waves (which bring the atom to the excited state) have an average energy below that of the fluorescence photons emitted in the atomic de-excitation process. In 1988, it was usually assumed that the minimum temperature that could be achieved by laser-cooling atoms was determined by the natural width of the excited state involved in the cooling process, i.e., of the order of a few mK. However, Phillips and coworkers at the National Institute of Science and Technology (NIST) near Washington DC, showed that it was in fact possible to cool atoms far beyond this limit down to temperatures in the microKelvin range. This observation was eventually interpreted in terms of an approach, deve loped independently by Cohen-Tannoudji and Dalibard in Paris and by Chu and coworkers in Stanford, which accounted for the fact that the ground level of the ato mic transitions used in the experiments had an internal structure consisting of several magnetic sub-levels [1]. 7.2% topic match

[141] ATOM TRAPPING IN DEEPLY BOUND STATES OF A FAR-OFF-RESONANCE OPTICAL LATTICE D. L. Haycock, ..., and P. Jessen Physical Review A 1997 - 19 citations - Show abstract - Cite Abstract: The ac Stark shift ~light shift! arising in laser interference patterns can be used to create stable periodic potentials for neutral atoms. Under appropriate conditions these ‘‘optical lattices’’ will laser cool and trap atoms in individual optical potential wells, with center-of-mass motion in the quantum regime. Experiments have explored a number of such lattice configurations in one, two, and three dimensions, and detailed insight into the dynamics of cooling and trapping has been gained through probe absorption and fluorescence spectroscopy @1#. The possibility of atomic confinement deep in the Lamb-Dicke regime suggests that it is worthwhile to pursue schemes for resolved-sideband Raman cooling @2# and quantum-state preparation @3#, as recently demonstrated for trapped ions. In a standard optical lattice formed by near-resonance light, control of the center-of-mass motion is limited by rapid laser cooling and heating processes that occur at a rate determined by photon scattering. These dissipative processes are readily avoided when the lattice is formed by intense light tuned far from atomic transition. Such far-off-resonance lattices have been used extensively in atom optics as diffraction gratings and lenses @4# and as model systems in which to study quantum chaos @5# and quantum transport @6#. When far-off-resonance optical lattices are used to trap atoms, however, the absence of built-in laser cooling makes it difficult to obtain vibrational excitation and confinement comparable to the near-resonance case. Accordingly, experiments on faroff-resonance lattices have so far achieved low vibrational excitation only by allowing the majority of vibrationally excited atoms to escape @7#. We demonstrate here a loading scheme, in which cesium atoms are first cooled and trapped in a near-resonance lattice, and then adiabatically transferred to a superimposed far-off resonance lattice. Immediately following transfer we achieve trapping parameters comparable to the near-resonance case, with a mean vibrational excitation as low as n ¯ ’0.3, and a typical rms position spread of Dz’l/20. Based on the lattice parameters we calculate an off-resonance photon scattering rate of order 10 3 s 21 .W e 7.1% topic match

[149] The super cool atom thermometer D. Hucul, ..., and W. Ketterle Journal Not Provided 2009 - 0 citations - Show abstract - Cite Abstract: The conquest of the cold has become one the most exciting goals in modern atomic physics. The development of laser and evaporative cooling techniques have been among the greatest achievements in the second half of last century, as recognized by two Nobel prizes on these topics (1997 and 2001). These methods made it possible to reach temperatures of the order of a few nK and led to the first experimental realization of a BoseEinstein condensate [1, 2] and a quantum degenerate Fermi gas [3] in dilute atomic vapors. Even though nK temperatures may seem extremely low, they are still too high for various potential applications, and the battle for reaching lower and lower temperatures in ultracold atoms continues. One of the driving forces for achieving even lower temperatures is Richard Feynman’s pioneering idea of a quantum simulator [4] wherein the behavior of a complex quantum system can be simulated by another quantum system. For instance, we want to load atoms in optical lattices (light shift potentials created by the interference of multiple laser beams) and use them to mimic the physics of electrons in solid-state crystals [5]. The optical lattice supplies the periodic potential in which atoms move. Bosonic (Fermionic) atoms in optical lattices are actually a perfect implementation of Bose (Fermi) Hubbard Hamiltonians [6], which describe particles hopping on a lattice with onsite interactions [7]. It is believed that these are the simplest models that contain the fundamental ingredients required to describe the behavior of strongly correlated materials, including, for example, quantum magnets or high-temperature superconductors. However, since atoms are much heavier than electrons, and since typical optical lattice interwell spacings are of the order of 104 times the ionic lattice spacings, temperatures below 10−2 nK are required in cold-atom laboratories in order to probe the same physics that occur at Kelvin temperatures in solid-state systems. The capability of reaching such low temperatures has to be accompanied by the development of new thermometers capable of measuring them. In a recent paper published in Physical Review Letters, David Weld and colleagues at the MIT-Harvard center for ultracold atoms [8] now report a new thermometry method for ultracold atoms in lattices, with the potential to measure temperatures as low as tens of pK. To date, typical bosonic cold-atom experiments in a single trap without an optical lattice have determined temperature from fits to absorption images of the expanded gas [9]. The data are fit to a bimodal density distribution. The area under the central peak, linked to the Bose-condensed fraction, and a Gaussian fit to the wings, which assumes noninteracting thermal atoms are combined to infer temperature. This technique has been very successful in a broad range of experimentally relevant temperatures, however, when atoms are loaded into optical lattices its regime of applicability reduces considerably. When atoms are loaded into a lattice they acquire an effective mass, which exponentially increases with the depth of lattice potential. As a consequence, the diluteness condition, which requires a small ratio between the mean interaction energy per particle to its kinetic energy, becomes invalid as the lattice potential depth is ramped up and the system enters the strongly correlated regime. Beyond a critical lattice potential depth, the average kinetic energy required for an atom to hop from one site to the next, J, becomes insufficient to overcome the interaction energy cost, U, and atoms tend to get localized at individual lattice sites, forming the so-called Mott insulator [10]. In a homogeneous system, Mott insulating phases occur only at integer densities; noninteger density contours lie entirely in the superfluid phase because there is always an extra particle that can hop without energy cost. In the presence of an additional parabolic trapping potential, both phases can coexist and the system 6.8% topic match

[151] Temperature limits in laser cooling of free atoms with three-level transitions F. Cruz, ..., and W. C. Magno 2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC 2013 - 0 citations - Show abstract - Cite Abstract: Summary form only given. We consider laser cooling of free atoms with simultaneous two-color excitation of three-level cascade transitions [1], [2], [3], [4], [5], [6] finding theoretically that temperatures below the Doppler limits associated with each one of the individual transitions are obtained. We use standard laser cooling analysis [7], [8] and the dressed state picture in order to identify different cooling regions, and determining optimum parameters for guiding further experiments. These new “sub-Doppler” limits are reached at the two-photon resonance where a significant increase of the damping coefficient and decrease of the diffusion take place. In the dressed state picture, this point corresponds to a crossing of the narrow and a (partially) dark state.Figure 1 shows a plot of temperature (normalized to the Doppler limit for cooling only on the lower transition) as function of single-photon detunings, for the 1S0-1P1-1D2 transition of Magnesium, in which the lower 1S0-1P1 transition is the usual cooling one (λ1 = 2πc/ω1 = 285 nm, λ2 = 2πc/ω2 = 881 nm, γ1 = 2π 78.8 MHz, γ2 = 2π 2.2 MHz). A minimum temperature of 38 μK is predicted. This temperature is lower than the Doppler temperature of the lower and upper transitions, TD = γ/k = 1.9 mK and 49 μK respectively. Due to the asymmetric absorption profile of the dressed atom, there is a remarkable increase in the damping coefficient (α) associated with the narrow transition, in comparison with the broad transition (two-level cooling). The cooling and damping times, inversely proportional to α, are reduced by the same amount. Since the curve for the diffusion coefficient (D) has the same shape as the curve for the absorption coefficient or the population of the intermediate state, D is also reduced with respect to the broad resonance, We analyze situations previously implemented experimentally in alkaline-Earth atoms using cascade transitions, and also discuss prospects for Aand V-type three-level systems. 6.7% topic match

[174] CREATION OF COLD AND DENSE ENSEMBLES OF CALCIUM ATOMS W. Ertmer Journal Not Provided 2009 - 0 citations - Show abstract - Cite Abstract: The behavior of cold calcium atoms in a suitable optical dipole trap was investigated. Processes which limit the phase-space density of the calcium ensemble, stored in the dipole trap, were identified and investigated. The ground state scattering length was experimentally determined. The consideration of these results allowed to discuss the perspectives for the realization of a calcium Bose-Einstein condensate. The realized dipole trap is compatible with the laser cooling on the narrow intercombination transition 4s S0 → 4s4p P1 at 657 nm. The atoms are cooled and stored in a magneto-optical trap (MOT) operating on the intercombination transition. The transfer of the atoms from the MOT into the dipole trap is limited by density dependent losses, caused by the 657 nm radiation. This laser light induces the photoassociation of Ca2 molecules, which can not be trapped in the dipole trap. The respective two-body loss rate and the capture rate of the dipole trap as well as the loss rates of the MOT could be combined in a model, which describes the loading dynamics of the dipole trap. A maximum phase-space density of 0.045 could be realized in the crossing region of two dipole traps, which are spatially overlapped. The number of particles in the crossing region is limited by inelastic three-body losses, whose loss rate is more than one order of magnitude smaller in comparison to the rate of elastic collisions. The loading dynamics of the crossing region is described by a model, which considers the different rates. The ground state scattering length was determined by photoassociation spectroscopy at the 4s S0 + 4s4p P1 asymptote. In comparison to previous measurements the improved experimental conditions allowed to investigate with the photoassociation spectroscopy an enlarged range of internuclear separations. This was accompanied with a more accurate determination of the scattering length. Its value covers a range between 340a0 and 700a0 and resolves therefore the discrepancy between the results of previous measurements. As a result of the presented investigations it is now clear, which most promising methods can be employed to reach a calcium Bose-Einstein condensate with a number of fascinating novel research opportunities. 6.1% topic match

[191] A new apparatus to simulate fundamental interactions with ultracold atoms Giacomo Colzi Journal Not Provided 2018 - 0 citations - Show abstract - Cite Abstract: In this thesis I present the construction of a new apparatus aimed at studying two-component Bose-Einstein condensates (BECs) in the presence of a Rabi coupling, where the two components correspond to internal states of sodium atoms. The coherent mixture, in the miscible regime, also exhibits a metastable excitation consisting in a domain wall of relative phase connecting vortices of different components. Due to the peculiar energy dependence of such a configuration, an attractive force, independent of the vortex distance, is expected, making this system a candidate for mimicking features of quark confinement in QCD. The surface tension of the domain wall structure can be experimentally controlled via the strength of the coupling, allowing to study the system dynamics in different regimes. These include a predicted regime in which, for sufficient high coupling strength, the domain wall breaks and new vortex couples nucleate, providing by itself an interesting experimental realization of spin counterflow dynamical instabilities in a superfluid system, as well as a phenomenon analogous to string breaking in QCD. The choice of sodium as atomic species is motivated by its collisional properties that allow to obtain a perfect spatial superposition between the two miscible components |F = ±1⟩ if trapped by a spin-independent potential, avoiding the known phenomenon of ’buoyancy’. Studying the dynamics of such systems for sufficiently long times, with a mixture subject to Zeeman differential energy shifts, requires a specific effort to remove magnetic field fluctuations: a rough estimate suggests that in order to maintain the system coherence for a sufficiently long time to study its dynamics, magnetic field fluctuations should be reduced by at least three orders of magnitude compared to typical values observed in laboratory environment. Such attenuations can be obtained by means of multiple layers of μ-metal, that is incompatible with the use of ordinary magnetic traps, characterized by large magnetic field gradients on the atoms, due to residual magnetization and saturation of the shielding material. To avoid such effects it is required to either evaporatively cool atoms into an optical dipole trap loaded from a molasses stage, or a hybrid approach by means of which atoms are transferred to a low-gradient quadrupole trap superimposed to the optical trap. Producing BECs with such protocols greatly benefits from an efficient optical molasses cooling stage to prepare the sample in the best conditions of temperature and density before loading atoms into the trap. With this regard, the main limitation of ordinary laser cooling techniques is their reliance on absorption and spontaneous emission cycles, which limits the lowest temperature and highest density that can be reached as a consequence of residual heating effects and photon-reabsorption. An important resource to cope with these limits are dark states. In a broader sense a dark state is a state which does not interact with the exciting light field, and an atom in such a state would be neither subject to the beneficial cooling effects nor to the detrimental effects of light scattering. It is possible, however, to exploit the phenomenon of electromagnetically induced transparency (EIT) to induce a velocity-selective cooling mechanism for which slower atoms, that do not need further cooling, are trapped in a dark state corresponding to a coherent superposition of atomic levels whose excitation probabilities interfere destructively, while the cooling mechanism still applies to the fastest atoms. Among these techniques, gray molasses cooling allows to reach temperatures as low as a few recoil temperatures, while retaining atomic densities useful to reach quantum degeneracy in the subsequent stages of the experiment. In order to exploit this technique, an additional laser source had to be implemented during my thesis. To realize a gray molasses on the sample only |F⟩ → |F − 1⟩ or |F⟩ → |F⟩ transitions can be chosen, requiring blue-detuned laser, in contrast to ordinary (sub)Doppler laser cooling techniques. Both these requirements rule out the use of the D2 transition used for ordinary laser cooling techniques, due to its finely-spaced hyperfine structure. On the other hand, the D1 transition is characterized by a broader level spacing in the hyperfine structure and the absence of higher energy states on the blue side of the |F = 2⟩ → |F' = 2⟩ transition. As part of the work for this thesis, I successfully implemented and characterized gray molasses cooling on the D1 optical line of sodium. The buildup of the new apparatus includes the assembly of a new laser source for laser trapping and cooling on the D2 line, the assembly of the optical table devoted to the frequency and amplitude control of all the laser beams involved in the optical laser cooling procedures as well as the electronic control system. Design and assembly of the UHV and baking procedures for the stainless steel vacuum chamber are also described as well as the laser cooling techniques employed to load the atoms in a Dark-Spot MOT. Regarding the production of BEC, various strategies were attempted for different dipole beam configurations. Dipole traps typically suffer from the tradeoff between capture volume and trap depth at a given power, while hybrid traps usually take advantage of a magnetic trap stage that would not be compatible with the μ-metal shielding. Preliminary attempts to reach quantum degeneracy after directly loading the dipole trap from molasses were unsuccessful due to spurious effects. An alternative approach based on a magnetic-shield compatible hybrid trap protocol, in the absence of magnetic trap compression, was successfully implemented. 5.4% topic match

[194] Two-stage crossed beam cooling with 6Li T. Luan, ..., and Zhaoyuan Ma Journal Not Provided 2015 - 0 citations - Show abstract - Cite Abstract: Applying the direct simulation Monte Carlo (DSMC) method developed for ultracold Bose-Fermi mixture gases research, we study the sympathetic cooling process of 6Li and 133Cs atoms in a crossed optical dipole trap. The obstacles to producing 6Li Fermi degenerate gas via direct sympathetic cooling with 133Cs are also analyzed, by which we find that the side-effect of the gravity is one of the main obstacles. Based on the dynamic nature of 6Li and 133Cs atoms, we suggest a two-stage cooling process with two pairs of crossed beams in microgravity environment. According to our simulations, the temperature of 6Li atoms can be cooled to T = 29.5 pK and T/TF = 0.59 with several thousand atoms, which propose a novel way to get ultracold fermion atoms with quantum degeneracy near pico-Kelvin. © 2015 Optical Society of America OCIS codes: (020.0020) Atomic and molecular physics; (020.2070) Effects of collisions; (020.7010) Laser trapping.

Jiang https://doi.org/10.1360/sspma-2020-0056 2020 - 0 citations - Show abstract - Cite Abstract: With the rapid development of the laser cooling techniques, we can realize coherent quantum state manipulation of atoms. Invaluable results, such as topological phase transitions with artificial gauge fields, phase transitions induced by many body interaction, the atomic fountain frequency standard, the gravity constant using an interferometer, the magic wave optical lattice frequency standard, the cold ion frequency standard and the cold atom gravimeter and gyroscope results, have been obtained with respect to various applications, including quantum phase transitions, simulation of the novel quantum states, and precise measurement of the cold atoms. The laser cooling techniques frequently break the previous accuracy records; thus, they are gradually setting the new quantum measurement standards. In addition, some of these techniques play vital roles in geological prospecting and national defense. In this review, we will focus on the novel quantum states induced by laser cooling and the corresponding phase transitions as well as the optical detection and manipulation of the quantum phases. To be specific, the energy spectrum in a Bose-Einstein condensate (BEC) with spin-orbital angular momentum coupling is discrete, and a first-order phase transition can be observed between the states having different angular momentums. We investigated the topological phase transitions induced by the many-body interactions, in which we observed that when using different filling numbers and interactions, topological phase transitions can be observed in a hexagonal optical lattice with high orbitals and different topological states can be indexed using the Chern numbers. Further, based on our investigation, we observed the occurence of a quantum phase transition between the novel superfluid states, i.e., the Fulde-Ferrell-Larkin-Ovchinnikov superfluid states to the Sarma superfluid states, owing to the imbalanced Feshbach resonance. Finally, we developed methods to measure the optical spectrum of the nP Rydberg states of the 87Rb atoms and detect the quantum states in optical lattices; in addition, we constructed a multicomponent BEC interferometer. 4.3% topic match

Foot Journal Not Provided 2010 - 0 citations - Show abstract - Cite Abstract: This thesis describes the design, construction and optimisation of a new apparatus to produce Bose-Einstein condensates (BECs) of 87Rb atoms. The main aim in building this system was to include a high resolution imaging system capable of resolving single atoms. Optical access for the imaging system was created by including a stage of atom transport in which the atoms are magnetically transferred ~50 cm from a magneto-optical trap (MOT), where they are initially collected, to a glass science cell where experiments are carried out and imaging takes place. Two magnetic transport schemes have been demonstrated, based on approaches first used in other laboratories. First, a scheme in which the atoms are transferred in a moving pair of magnetic trapping coils. Second, a hybrid scheme where the atoms are translated part of the distance in the moving coils, and the rest of the way by switching the current in a chain of fixed coils. This second scheme was designed to allow optical access for a high numerical aperture microscope objective to be placed immediately next to the science cell for high resolution imaging.The atoms were first collected in a large pyramid MOT which can be loaded with 3 × 10^9 atoms in a time of 20 s. Around half of these atoms – those in the |F = 1, mF = −1> magnetic substate – were then magnetically trapped prior to transport. The typical fraction of the trapped atoms transferred to the science cell was ~30% and ~18% for the moving coils and hybrid schemes respectively.Evaporative cooling was carried out on the atom cloud following transport with the moving coils and loading into a time-orbiting potential trap. The optimised cooling sequence lasted for 28 s and consistently produced a pure condensate with 5 × 10^5 atoms. A BEC has also been produced by evaporative cooling following hybrid transport. The next experimental steps will be to optimise the hybrid transfer approach further and install the high resolution imaging system.The system is well-placed to continue an ongoing series of experiments in which ultracold atoms are trapped in RF-dressed potentials. These potentials will be used to study low-dimensional quantum gases as well as in experiments where small atom number BECs are rapidly rotated to enter the fractional quantum Hall regime. 3.9% topic match

[259] Ultra-cold atomic magnetometry: realisation and test of a ⁸⁷Rb BEC for high-sensitivity magnetic field measurements M. Venturelli Journal Not Provided 2018 - 1 citations - Show abstract - Cite Abstract: The development of an experimental apparatus to produce Bose-Einstein condensates (BECs) of ⁸⁷Rb atoms and their application to magnetometry are discussed. Optical detection of atomic Larmor precession is a widely explored method for high-sensitivity measurements of magnetic fields. In this context, short laser/atom interaction time, atomic thermal diffusion and decoherence effects are among the main limitations. In this thesis, we overcome such problems by using spin-polarised ⁸⁷Rb ultra-cold atoms as the sensing element. After the atoms are polarised, a resonant pulse of radio-frequency excites Larmor precession, which is sensitive to external magnetic fields. By measuring the perturbations of the radio-frequency induced spin precession, information on the magnetic fields of interest. This is achieved by monitoring the polarisation plane’s rotation of a linearly polarised resonant laser probe. In the first part of this thesis, the building and optimisation of a laser-cooling set up to obtain a BEC in a hybrid trap is reported. In order to achieve the Phase Space Density (PSD) required for BEC, several different stages of trapping and cooling are necessary. Each phase has been implemented and optimised. The first step consists in the magneto-optical trap (MOT). Here a velocity dependent damping force and a spatially dependent confining force give the largest changes in PSD. Then atoms are loaded into a hybrid trap obtained by overlapping a quadrupole magnetic potential and a far detuned optical crossed dipole trap. The final stage for the condensation consists of forced evaporative cooling, both via magnetic and optical evaporation. In the second part of the thesis, a general overview of the principles of optical atomic magnetometry is provided and the advantages of using ultra-cold atoms with respect to conventional thermal vapours are discussed. The implementation, operation and a preliminary characterisation of the ultra-cold atom magnetometer are described along with the preliminary results collected. Finally, a plan for future improvements of its sensitivity is presented. 2.7% topic match

Orozco Journal Not Provided None - 0 citations - Show abstract - Cite Abstract: We have used diffraction gratings to simplify the fabrication, and dramatically increase the atomic collection efficiency, of magneto-optical traps using micro-fabricated optics. The atom number enhancement was mainly due to the increased beam capture volume, afforded by the large area (4 cm 2) shallow etch (∼ 200 nm) binary grating chips. Here we provide a detailed theoretical and experimental investigation of the on-chip magneto-optical trap temperature and density in four different chip geometries using 87 Rb, whilst studying effects due to MOT radiation pressure imbalance. With optimal initial MOTs on two of the chips we obtain both large atom number (2 × 10 7) and sub-Doppler temperatures (50 µK) after optical molasses.

[291] Finite Temperature Effects in Ultracold Fermi Gases K. Evin Journal Not Provided 2006 - 3 citations - Show abstract - Cite Abstract: The study of ultracold trapped fermionic gases is a rapidly e xploding subject [1-10] which is defining new directions in condensed matter and atomic physi cs. It has also captured the attention of physicists who study color superconducting quark matter as well as nuclear matter [11-13]. Indeed, it is hard, in recent times, to find a subfield of physic s which appeals this broadly to the research community. As we come to understand the gases, e xperimentalists will move to address fermionic atoms in optical lattices; this will prov ide important insight to condensed matter physicists as analogue systems for “solving” intrac table many body problems. What makes these gases (and lattices) so important is their r emarkable tunability and controllability. Using a Feshbach resonance, one can tune the a t ractive two-body interaction from weak to strong, and thereby make a smooth crossover from a BCS superfluid to a Bose-Einstein condensation (BEC) [14, 15]. Not only does this allow high tr ansition temperatures Tc (relative to the Fermi energy EF ) but it may also provide insights into the high temperature c uprate superconductivity [16-19]. Furthermore, one can tune the p opulation of the two spin states, essentially at will, in this way, allowing exploration [20-22 ] of exotic polarized phases such as the FFLO [23-25] superfluids, of interest to condensed matter, n uclear and particle physicists. One will be able to tune the lattice parameters such as bandwidth , on-site repulsion, even random disorder, etc and thereby study the famous, and as yet, unsol ved Hubbard model Hamiltonian. This paper will concentrate on those issues relating to the e ffects which are of current interest to experimentalists. In particular, we will study BCS-B EC crossover in atomic Fermi gases, looking at a wide range of different experiments. Our group h as been principally interested in the effects of finite temperature [26, 17, 18] and in this revi ew, we will discuss how temperature T enters into the standard crossover theory, and how temperat ur can be measured, and how tem- 1.8% topic match

[295] Laboratory Apparatus Generates Dual-Species Cold Atomic Beam R. Thompson, ..., and D. Enzer Journal Not Provided 2004 - 0 citations - Show abstract - Cite Abstract: A laser cooling apparatus that generates a cold beam of rubidium and cesium atoms at low pressure has been constructed as one of several intermediate products of a continuing program of research on laser cooling and atomic physics. Laser-cooled atomic beams, which can have temperatures as low as a microkelvin, have been used in diverse applications that include measurements of fundamental constants, atomic clocks that realize the international standard unit of time, atom-wave interferometers, and experiments on Bose-Einstein condensation. The present apparatus is a prototype of one being evaluated for use in a proposed microgravitational experiment called the Quantum Interferometric Test of Equivalence (QuITE). In this experiment, interferometric measurements of cesium and rubidium atoms in free fall would be part of a test of Einstein s equivalence principle. The present apparatus and its anticipated successors may also be useful in other experiments, in both microgravity and normal Earth gravity, in which there are requirements for dual-species atomic beams, low temperatures, and low pressures. The apparatus includes a pyramidal magneto-optical trap in which the illumination is provided by multiple lasers tuned to frequencies characteristic of the two atomic species. The inlet to the apparatus is located in a vacuum chamber that contains rubidium and cesium atoms at a low pressure; the beam leaving through the outlet of the apparatus is used to transfer the atoms to a higher-vacuum (lower-pressure) chamber in which measurements are performed. The pyramidal magneto-optical trap is designed so that the laser cooling forces in one direction are unbalanced, resulting in a continuous cold beam of atoms that leak out of the trap (see figure). The radiant intensity (number of atoms per unit time per unit solid angle) of the apparatus is the greatest of any other source of the same type reported to date. In addition, this is the first such apparatus capable of producing a slow, collimated beam that contains two atomic species at the same time. 1.7% topic match

[314] Investigating the dynamics of a Bose Einstein condensate on an atom chip I. Barr https://doi.org/10.25560/26226 2015 - 5 citations - Show abstract - Cite Abstract: In this thesis I discuss work that has been carried out on the dynamics of a Bose Einstein condensate of Rb 87 produced near an atom chip. A Bose Einstein Condensate (BEC) is a quantum state of matter where a single quantum state becomes occupied by a macroscopic number of identical Bosons. In our case this is achieved by cooling a system of trapped identical rubidium 87 atoms to its ground state. To reach temperatures of condensation we initially laser cool atoms from room temperature, before loading them into a magnetic trap. The magnetic trap is produced through a combination of uniform magnetic fields from coils outside our vacuum chamber and currents running through wires on an atom chip. The atom chip is a microfabricated device, produced by a coating a silicon chip with a thin layer of gold and etching wires into it. Together, these fields create a magnetic field minimum 120μm from the surface of the chip which can be used to confine low field seeking hyperfine states of the atom in an elongated harmonic trap. Once the atoms are confined in the magnetic trap we used force evaporative cooling out to reach the phase space densities required for Bose Einstein condensation. The BEC is used to investigate the relative dynamics between the fraction of the atoms in the condensate to those not in the condensate. Our atom chip provided a suitable environment to investigate this due to fragmentation of the magnetic potential close to the chip. Small imperfections in the wires on our atom chip mean that the trapping potential isn’t smooth. Small regions of higher trapping frequency or fragments are formed. Due to the small size of these fragments it is possible to find a position where a condensate can form in the fragment, and see a potential of high frequency, whereas a non-condensed atom will see a lower frequency potential. We exploit this to set the condensed fraction moving relative to the non condensed part and investigate the subsequent damping of their motion relative to each other. 1.4% topic match

[323] Signatures of superfluidity in atomic Fermi gases M. Pinilla Journal Not Provided 2003 - 3 citations - Show abstract - Cite Abstract: After the experimental realization of Bose-Einstein condensation in dilute gases of alkali atoms, experimentalists started to trap the fermionic isotopes. The degenerate state for fermions was reported in 1999. The main objective of these experiments is to obtain superfluidity of fermionic gases. When there are attractive interactions between the fermions, the Fermi sea becomes unstable with respect to the formation of atomic Cooper pairs and the system becomes a superfluid. It turns out that the existing experimental cooling techniques allow minimum temperatures for fermions of the order of the Fermi temperature. Using Feshbach resonances induced by magnetic fields enhances the effective interactions between the atoms leading to superfluid transition temperatures of the order of the Fermi energy. This is a completely new regime of fermionic superfluidity far from the BCS superconductors, He and even highsuperconductors. The achievement of superfluidity on gases of fermionic alkalis is currently being pursued in many experimental groups. In this thesis, different signatures of the superfluid transition have been considered. The use of almost on-resonant laser light for coupling between the different internal states of the atoms as a method for probing superfluidity has been analyzed. Coupling between the paired states has been proposed as a way to directly detect the Cooper pair size. The Josephson effect, related to the phases of two coupled superfluids, is shown to present an asymmetry when the internal states of the atoms forming the pairs are coupled with different detunings. Vortices, intimately related to superfluidity, have also been considered. The single vortex solution of the Ginzburg-Landau equation for the superfluid order parameter has been numerically computed and a new vortex core size reflecting the trapping geometry has been obtained. Bloch oscillations have been analyzed for fermionic atoms both in the degenerate regime and in the superfluid regime. Superfluidity is found to supress the amplitude of the Bloch oscillations. 1.2% topic match

[336] Deceleration of Molecules M. Pospiech Journal Not Provided 2004 - 0 citations - Show abstract - Cite Abstract: Cold conditions are in principle advantageous, because they mean longer observation and interaction times. With cold conditions some fundamental studies can be done with molecules: high precision spectroscopy, cold molecule–molecule collisions, cold chemistry and molecular Bose-Einstein condensation. Laser cooling is very successful with atoms. The deceleration principle can be described very simplified as deceleration by momentum transfer from a laser-beam under the condition of an absorption-emission cycle in the atom. We find however that molecules are distributed over vibrational states after spontaneous emission, so that it is very difficult to find a closed two-level system in molecules. Laser cooling can thus not be applied for molecules. The principle setup of the experiments is the following: First bunches of molecules are provided with a supersonic pulsed valve. The gas expansion cools all internal energies and produces bunches with a high average velocity, but very narrow velocity distribution. After exciting the valve the stream of molecules is spatialy selected with a skimmer and afterwards prepared with a laser beam if necessary. In the following they fly through the Stark decelerator and are finally detected with a time of flight method. Molecules possessing an electric dipole moment gain Stark energy upon entering an electric field when in an appropriate quantum state. This gain in Stark energy is compensated by a loss in kinetic energy. If the electric field is greatly reduced before the molecule has left the electric field the molecule will not regain the lost kinetic energy. By letting the molecule pass through multiple pulsed electric fields they can thus be slowed down and brought to a standstill. The molecules experience additionally a force in the inhomogeneous electric fields towards the minimum electric field (low-field seeking state). This leads to focusing of the beam. This idea is realized in the ‘Stark Decelerator’. This consists of several stages of cylindrical rods placed equidistantly, alternately horizontally and vertically positioned. The fields on the rods are on the order of 10 kV, with fields of 120-200 kV. In order to decelerate properly the bunch of molecules must be kept together throughout the decelerator. This requires, that the timing sequence of the pulsed field is chosen such that the »bunch« of molecules always has the same phase, i. e. , that the bunch of molecules is always centered around the same equilibrium position on the slope of the potential hill when the fields are switched. Therefore one has to lower the velocity of the potential well, by gradually increasing the time intervals after which the electric fields are being switched. The time of flight (TOF) measurements show that only a small velocity distribution centered around the central velocity is captured and molecules outside the interval are not affected. This means that only a subset of molecules is decelerated. This deceleration method is applicable for molecules with sufficient large positive Stark shift in experimentally feasible electric fields, sufficient low initial kinetic energy and sufficient low mass/Stark energy. It has been demonstrated so far with CO, NH3 (Ammonia), OH, and YbF. 1.0% topic match

[349] Preface: special topic on cold atoms Jun Ye National Science Review 2016 - 0 citations - Show abstract - Cite Abstract: For several decades, Atomic,Molecular, andOptical Physics has undergone and is still going through a renaissance. Research on cold atoms has played a key role in a profound transformation of this traditional field. Ultracold atoms allow us to reach down to the core of AMO physics where detailed knowledge of atomic andmolecular structure forms the foundation for understanding light–matter interactions. This understanding then fuels the development of increasingly sophisticated control of individual quantum systems. The increasing ability for quantum control has stimulated the simultaneous, rapid development of the state-of-the-art lasers. These activities have not only dramatically advanced the frontier of precision measurement, but also enabled explorations of increasingly complex quantumphenomenawhere fundamental connectionsbetween few-bodyand many-body physics are probed. The desire for improved control of atomic motions for spectroscopy applications motivated the early development of laser cooling in 1980s. In a personal interview for this special topic, W.Phillips, oneof the pioneers of laser cooling, gives an intimate accountof how thefield started alongwith thebroad rangeof scientific and technological innovations that have ensued. For example, one imaginative andpractical application of cold atoms is radio-krypton dating. As described in a perspective by Z.-T. Lu, the exquisite isotope selectivity and detection efficacy for single trapped atoms have provided a unique background-free–tracedetection capability for earth science applications. In another application where high-quality atomic transitions in the optical domain are used for the new-generation optical atomic clocks, preserving the maximum coherence between atomic states and anoptical field requires that the atomic center-of-massmotion is controlled at the scale of an optical wavelength and that the optical probe of internal atomic states do not introduce measurement uncertainty fromphoton recoils.Meeting these challenges demands preparing atoms at ultralow temperatures and confining them in traps that decouple the atomic internal and external degrees of freedom.The full control of both internal and external dynamics is critical for precisionmeasurement, frequency metrology (discussed in a review by X. Zhang and J. Ye), and quantum information science. It is now routine to prepare, manipulate, and measure cold atoms in the formof quantumdegenerate gases inwhich striking quantumbehavior dominates the observation of systemdynamics. Two important tools have been invented to enrich quantum physics in strongly interacting regimes: the first powerful tool is the control of interatomic scattering resonances, and thus interactions, via the Feshbach resonance. A perspective by C. Chin beautifully illustrates the transition from a weakly interacting quantum system to a strongly interacting one, where new universal principles can be explored that govern correlated quantum behavior. The second useful tool is the introduction of optical lattices to regulate atomicmotions, which provides an intimate interface betweenultracold atoms and condensed-matter systems. A perspective by S. Kuhr shows the powerful in-situ visualization of individual atoms confined in an optical lattice via a recently developed technique of a quantum gas microscope, which is opening a new approach to the study of many-body quantum systems. With these tools closely integratedwithwell prepared atomic quantum systems, we are ready to take on challenging and outstandingexperiments toprobe the connectionbetween twoand few-body physics and to understand the emergence of quantum many-body correlations. A research highlight by A. M. Rey discusses the importance of introducing synthetic gauge fields to ultracold atoms and turning them into a versatile playground for simulating and gaining insights to new classes of quantummaterials. A reviewbyM.Weidemuller explores recent developments of resonant three-body Efimov effects in ultracold heteronuclear atomic mixtures, helping illuminate universal three-body physics and atom-molecule interactions. Plus, polar molecules have been cooled to quantum gases. The rich internal structure of these molecules provides a unique experimental testing ground for the fundamental laws of nature. They also provide new opportunities for the study of novel many-body quantum systems with tunable, long-range, and anisotropic interactions. The strong interdisciplinary character of these new atomic andmolecular systems facilitates powerful connections to other scientific fields, including chemistry, quantum information, condensed-matter physics, and high-energy physics. Many new research opportunities are emerging. I sincerely thank the contributing authors who invested time and effort for this special topic, and I hope it will serve to inspire young researchers to develop more creative ideas and approaches. 0.8% topic match

[353] Formation of bright solitary matter-waves A. L. Marchant Journal Not Provided 2012 - 4 citations - Show abstract - Cite Abstract: This thesis presents the development of an experimental apparatus to produce Bose-Einstein condensates (BECs) with tunable interparticle interactions. The ability to precisely control the strength of these interactions, and even to switch them from repulsive to attractive, allows one to probe novel regimes of condensate physics, from the collapse of attractively interacting BECs and the formation of solitary matter-waves to the observation of beyond mean-field effects in strongly repulsive condensates. The construction and characterisation of both a single and crossed beam optical dipole trap is presented. In the single beam case we develop a technique allowing the guided transport of atoms along the beam and up to a room-temperature surface; a technique which can be used to evaporatively cool the trapped atomic cloud. We produce Bose-Einstein condensates of 87Rb in the F=1, mF=-1 state in this trap, comparing the effect of beam waist on the evaporation trajectory. In the crossed beam trap Bose-Einstein condensation of 87Rb is realised in three distinct trapping configurations, along with a 1D optical lattice formed by changing the polarisation of the beams. A method of direct cooling of 85Rb atoms in the crossed trap is developed using a magnetic Feshbach resonance to precisely tune both the elastic and inelastic scattering properties of the atoms. The resonance used for this work occurs at 155G in collisions between atoms in the F=2, mF=-2 state of 85Rb. Bose-Einstein condensates of up to 40,000 85Rb atoms are formed in this trap and we demonstrate the presence of tunable interatomic interactions, exploring the collapse phenomenon associated with attractive condensates. By loading the 85Rb condensate into a quasi-1D waveguide we show that stable attractive condensates can be created, taking the form of bright solitary matter-waves. We observe a solitary wave of ~2,000 atoms which propagates, without dispersion, along the waveguide over a distance of ~1.1mm. The particle-like nature of the solitary wave is demonstrated by classical reflection of the wavepacket from a repulsive Gaussian barrier. 0.8% topic match

[379] Study of an interacting Li6 molecular condensate P. Jouve Journal Not Provided 2019 - 0 citations - Show abstract - Cite Abstract: This thesis reports on a study of the molecular Bose-Einstein condensation (mBEC) of the 6Li. More specifically, using model the Hartree-Fock (HF) model to fit the spatial density of the cloud, we demonstrate that the thermal cloud deplete the condensate, therefore a lower temperature is needed to condense the atoms in the ground state. Moreover the inter-atomic interactions can be controlled via Feshbach resonance (see section 2.2), allowing us to study the effects of the interactions on the thermodynamics properties of a mBEC, especially the critical temperature of the BEC that decreases when we increase the inter-atomic interactions. The description starts from the experimental procedure to produce a mBEC to its physical analysis. We draw a list describing the different chapters presented in the thesis: Chapter 1 Introduction: We present the fundamental difference between fermions and bosons, and we give some example of realisations of Bose-Einstein condensation and degenerate Fermi gas. Chapter 2 Interactions in an ultracold gas: We discuss the role of interactions depending on the type of particles, either fermions or bosons, and the phenomena of Feshbach resonance which is a powerful tool to change the interaction strength between particles. Chapter 3 Degenerate quantum gas: A brief historical section gives the fundamental ideas that initiate the long story of the Bose-Einstein condensation phenomena. We then discuss the mathematical description of a BEC without interactions, which is the starting point of the theoretical analysis used in the chapter 3 where we study the influence of the interactions. Then, we describe the statistics of Fermi gas and the different states that can be reached using Feshbach resonances, in particular the creation of the Feshbach molecules. Chapter 4 Basics of Cold atoms physics: A toolbox of the necessary knowledge to understand the underlying phenomena and concepts used in a cold atoms experiment. We describe the kind of atoms used, how these atoms interact with a magnetic and an electromagnetic field. Chapter 5 Guideline to making a 6Li BEC: This chapter describes the experimental methods used in our laboratory to cool down atoms to the regime of ultra-cold temperature T < 1µK. This section gives details about atomic beams production, the Zeemann slower (radiation force cooling), the magnetooptical trap (MOT) (cooling b molasses), optical dipole trap (evaporative cooling). Also we present the methods used to probe atomic clouds, such as in situ imaging methods. My contribution to this section has been to improve the stability of the evaporative cooling sequence (see section 5.4.4) and to optimize the shape of the the evaporative cooling ramp (see section 5.4.1) in order to maximise the phase space density (PSD), to reach Bose-Einstein condensation. Then, to make precise simulations and measurements to extract values of the trapping frequencies (see section 5.4.5) and scattering length (see section 5.5.4), the latter gives us the interaction strength of the system. These parameter are then used in the next chapter to extract thermodynamics properties of the system. Moreover, I developed the sequence for in situ absorption imaging (see section 5.5.3). Chapter 6 Study of an interacting 6Li mBEC: This chapter discusses the theory to understand the thermodynamics properties of an interacting Bose6 Einstein condensate. It is accomplished by fitting the spatial atomic density profiles with different models, the ideal gas (IG) model, the semi-Ideal (SI) gas model and the Hartree-Fock (HF) model. These three models vary in complexity from the most simple one the IG model to most elaborated one the HF model. The HF model requires a lot more of computational power than the other methods, therefore we present a new numerical method requiring less computational power proposed by Nathan Welch, and demonstrate experimentally through a statistical analysis that the HF model used to determine the thermodynamics properties of a BEC is more accurate to describe utracold atomic gas near the transition. Then, we present the results of the influence of the scattering length on the transition temperature and the chemical potential. My contribution to this section has been to develop tools to analyse the in situ atomic density profiles and improve the fitting program of Nathan (see section 6.3). Also, after taking the measurement of the in situ atomic density profiles, I developed and used the tools for the analysis of the thermodynamics properties of the mBEC (see section 6.4). I also adapted the models described in [1] to our experiment to extract the value of the radius of the condensate (see section 6.5). Finally, with N.Welch we present method based on energy conservation to verify the validity of the different model, my principal contribution to this was to modify the experiment to use this method (see section 6.7). Chapter 7 Initial work: Double well with 6Li molecules: This chapter presents the initial work to produce a double well potential to trap cold atoms and create a Josephson Junction. We present the state of the art of the different effects that have been observed, and discuss future measurements that would be achievable in our laboratory, in particular we would like to use a second specie 133Cs as impurities and observe the influence on Josephson oscillations of 6Li molecules. An experimental description of the double well trapping potential has been implemented and is also described. My contribution to this section was to design and implement the double well trapping potential. 0.5% topic match

[390] Laser cooling of rubidium atoms in a magneto-optical trap S. Hopkins Journal Not Provided 1996 - 3 citations - Show abstract - Cite Abstract: This thesis describes theoretical and experimental work concerning radiation forces on atoms, with particular reference to rubidium atoms confined in a magneto-optical trap. After a short history of the field of laser cooling, a review of the semiclassical theory of mechanical interactions between two-level atoms and electromagnetic radiation is given. Different formulations of the semiclassical theory are discussed, including a new formulation in terms of momentum transfer amongst the plane wave modes of the electromagnetic field. Two important applications of light forces on atoms, namely 'optical molasses' and the 'magneto-optical trap', are then described with emphasis on experimental parameters. Three sub-Doppler cooling mechanisms, 'sisyphus cooling', 'motion-induced orientation cooling' and the 'magnetically-assisted sisyphus effect', are described and their role in optical molasses and the magneto-optical trap is discussed. A new study of the polarisation gradients which occur in 3-D monochromatic light fields is presented and quantifies their relative presence in different light field configurations. Polarisation gradient parameters are developed and shown to be directly related to the relativistic spin tensor of the light field. Implications of this polarisation gradient study for laser cooling work are discussed. The design, construction from scratch, operation and testing of a magneto-optical trap for rubidium are described, including novel designs for two vacuum cells. Preliminary experiments to characterise the trap are described and results are presented; they primarily concern the number and distribution of atoms in the trap. Finally. the theory of time domain spectroscopy is reviewed. The construction and testing of a pulsed dye laser for study of coherent transients in samples of laser-cooled atoms and a proposed experiment to measure the temperature of cold atoms using coherent transients are described. Factors expected to influence the shape of coherent transients in cold atoms are discussed. 0.4% topic match

[393] Cold collisions in dissipative optical lattices J. Piilo and K. Suominen Journal of Optics B-quantum and Semiclassical Optics 2004 - 1 citations - Show abstract - Cite - PDF Abstract: The invention of laser cooling methods for neutral atoms allows optical and magnetic trapping of cold atomic clouds in the temperature regime below 1 mK. In the past, light-assisted cold collisions between laser cooled atoms have been widely studied in magneto-optical atom traps (MOTs). We describe here theoretical studies of dynamical interactions, specifically cold collisions, between atoms trapped in near-resonant, dissipative optical lattices. The extension of collision studies to the regime of optical lattices introduces several complicating factors. For the lattice studies, one has to account for the internal substates of atoms, position-dependent matter–light coupling, and position-dependent couplings between the atoms, in addition to the spontaneous decay of electronically excited atomic states. The developed one-dimensional quantum-mechanical model combines atomic cooling and collision dynamics in a single framework. The model is based on Monte Carlo wavefunction simulations and is applied when the lattice-creating lasers have frequencies both below (red-detuned lattice) and above (blue-detuned lattice) the atomic resonance frequency. It turns out that the radiative heating mechanism affects the dynamics of atomic cloud in a red-detuned lattice in a way that is not directly expected from the MOT studies. The optical lattice and position-dependent light–matter coupling introduces selectivity of collision partners. The atoms which are most mobile and energetic are strongly favoured to participate in collisions, and are more often ejected from the lattice, than the slow ones in the laser parameter region selected for study. Consequently, the atoms remaining in the lattice have a smaller average kinetic energy per atom than in the case of non-interacting atoms. For blue-detuned lattices, we study how optical shielding emerges as a natural part of the lattice and look for ways to optimize the effect. We find that the cooling and shielding dynamics do not mix and it is possible to achieve efficient shielding with a very simple arrangement. The simulations are computationally very demanding and would obviously benefit from the simplification schemes. We present some steps in this direction by showing how it is possible to calculate collision rates in near-resonant lattices in a fairly simple way. The method can then be used to combine quantum-mechanical and semiclassical models for cold collision studies in optical lattices. 0.4% topic match

[398] Do Trapped Gases Actually Exhibit Bec? the Theory O. Boseeinstein Condensation O. Dilute Gases K. Burnett, ..., and C. Clark Journal Not Provided None - 0 citations - Show abstract - Cite Abstract: ose–Einstein condensation (BEC) has long been known to be a key element of macroscopic quantum phenomena such as supercon-ductivity and superfluidity. BEC per se, however, eluded direct and unquestioned observation until 1995, when experimental groups produced condensates in dilute atomic alkali gases. 1 The story of these BEC experiments, as recounted in the accompanying article by Wolfgang Ketterle (page 30), has many of the elements of a heroic fable. Success was founded on the ingenuity, skill, and determination of the heroes, but it was hastened by their acquisition of " magic weapons, " such as laser cooling, and by serendipity, such as having favorable values of fundamental atomic collision parameters. The only thing missing is the proverbial happy ending, for BEC itself has turned out to be a magic weapon that has launched other ambitious new quests during the subsequent four years. Difficult though it was at first to attain, BEC has been found to provide a robust and versatile platform for experiments on mesoscopic many-body physics. 2 It has pushed the ultima Thule of low-temperature physics into territory some five orders of magnitude colder than the mil-likelvin regime of the helium superfluids; offered novel perspectives on phenomena previously encountered only in those superfluids; and provided precise tests of some of the keystone theories of many-particle quantum systems. Moreover, it has led to the production of entirely new physical systems, such as mixed degenerate Fermi gases (see PHYSICS TODAY, October 1999, page 17), and has stimulated visions of extraordinary applications, such as coherent amplification of matter waves and table-top tests of finite-temperature quantum field theory. This article presents a current perspective on advances in the theoretical understanding of gaseous BEC from the standpoint of atomic, molecular, and optical (AMO) physics. In AMO physics, BEC is now perceived both as an enabling technology, yielding the same exquisite control of matter waves that is possible for light waves, and as a vibrant point of contact with other branches of physics. Much of the essence of BEC in trapped-atom systems is captured in concepts that are familiar to AMO physicists yet have rich parallels in condensed matter, statistical, and elementary particle physics. For example, the order parameter, introduced by Lev Landau as a unifying concept for understanding phase transitions, is manifested in dilute gas BEC as the condensate wavefunction (see the cover of this issue and figure 1), and it can be measured, … 0.3% topic match

[399] Ju n 20 00 Coherence properties of a continuous atom laser Y. Castin and R. Dum Journal Not Provided 2000 - 0 citations - Show abstract - Cite Abstract: We investigate the coherence properties of an atomic beam evaporatively cooled in a magnetic guide, assuming thermal equilibrium in the quantum degenerate regime. The gas experiences two-dimensional, transverse Bose-Einstein condensation rather than a full three-dimensional condensation because of the very elongated geometry of the magnetic guide. First order and second order correlation functions of the atomic field are used to characterize the coherence properties of the gas along the axis of the guide. The coherence length of the gas is found to be much larger than the thermal de Broglie wavelength in the strongly quantum degenerate regime. Large intensity fluctuations present in the ideal Bose gas model are found to be strongly reduced by repulsive atomic interactions; this conclusion is obtained with a one-dimensional classical field approximation valid when the temperature of the gas is much higher than its chemical potential, k B T ≫ |µ|. The first experimental achievements of Bose-Einstein condensates in atomic vapors [1, 2, 3, 4] have opened promising perspectives for atom optics: condensates constitute indeed atomic waves sources of much better coherence properties than the usual 'thermal' sources like the standard magneto-optical trap. These coherence properties have already been demonstrated experimentally: interferences experiments between two condensates have been performed at MIT [5] and at JILA [6], the first order correlation function of the atomic field has been measured in Münich [7], and suppression of density fluctuations (that is fluctuations in the intensity of the atomic field) has been revealed by a measurement of the mean-field energy [8] and of three-body losses [9]. By inducing a coherent leak of atoms out of trapped condensates several groups have succeeded in creating pulsed or quasi-continuous 'atom-lasers' [10]. For future applications the already realized 'atom-lasers' may suffer from the handicap of a low mean flux of atoms: the condensates were not experiencing any continuous loading of atoms, so that the coherent output of atoms terminated once the ∼ 10 6 atoms of the condensate were leaked out. As the repetition rate of the whole sequence is limited by the time required to form a condensate by evaporative cooling (on the order of seconds) the resulting mean flux of atoms is < 10 6 atoms/s. Several proposals have been made to refill the condensates with atoms in a continuous way [11] but they have to our knowledge not been realized yet. Recently we proposed a different scheme, based on the … 0.3% topic match

[401] A single apparatus for the production of ultracold fermionic lithium and cold bosonic caesium gases Asaf Paris Mandoki Journal Not Provided 2015 - 0 citations - Show abstract - Cite Abstract: Ultracold mixture experiments hold the promise of providing new insights into many-body quantum systems as well as ultracold chemistry and few-body phenomena. The work presented in this thesis dealt with the construction of a new apparatus for the production and study of ultracold gases of fermionic lithium-6 and bosonic caesium-133. These isotopes offer a wide tunability in their interaction strength, both in inter-species and intra-species collisions, through magnetic Feshbach resonances. Additionally, the widely different resonance frequencies of lithium and caesium enables independent control of each of the species. With this apparatus, Bose-Einstein condensates (BEC) containing 10^4 lithium Feshbach molecules are routinely produced. The cooling system for caesium has been developed in parallel and important steps towards producing ultracold caesium gases have been made. An optical dipole trap has been loaded with 2x10^6 caesium atoms and evaporative cooling towards quantum degeneracy can now be pursued. Laser, vacuum, magnetic and control systems have been developed for the implementation of this experiment. Light produced with this laser system was used to laser cool atoms, create conservative dipole traps as well as to provide means of imaging atomic clouds. Additionally, a system to produce strong magnetic fields of up to 1400 G has been established in order to exploit the wide tunability in the atomic interactions. Software that was developed for the computerised control system facilitated the coordination of all the components involved in the experimental sequence. Measurements and calculations that showcase the functionality of relevant parts of the setup are presented in this thesis. In this experiment, lithium and caesium atoms are obtained from a novel type of Zeeman slower and are loaded into a magneto-optical trap (MOT). The system is capable of doing this independently for each of the atomic species as well as sequentially. After the MOT has been loaded with atoms, they are transferred into a conservative far-off-resonance optical dipole trap. By adjusting the interactions between atoms and lowering the depth of the dipole trap, efficient evaporative cooling of lithium was carried out from which a molecular BEC was obtained. Time-of-flight measurements were used to characterise the condensate and study its expansion dynamics. 0.3% topic match

Hulet Physical Review A 1999 - 20 citations - Show abstract - Cite - PDF Abstract: A theoretical treatment of light scattering from a degenerate Fermi gas of trapped ultracold 6 Li atoms is presented. We find that the scattered light contains information that directly reflects the quantum pair correlation due to the formation of atomic Cooper pairs resulting from a Bardeen-Cooper-Schrieffer phase transition to a superfluid state. Evidence for pairing should be observable in both the space and time domains. @S1050-2947~99!09207-0# PACS number~s!: 03.75.Fi, 32.80.Pj, 67.40.Db The realization of Bose-Einstein condensation ~BEC! in trapped atomic gases @1# has generated interest in the atomic physics, quantum optics, and condensed-matter physics communities. Although the experimental realization of a degenerate atomic Fermi gas has not yet been demonstrated, interest in this subject is also increasing @2‐6#, and efforts to trap and cool 6 Li and 40 K gases into the quantum degenerate regime are underway in several laboratories. Of course, the behavior of a degenerate Fermi gas is remarkably different from that of a degenerate Bose gas. As in the BardeenCooper-Schrieffer ~BCS! theory of superconductivity in metals, it has been predicted that a degenerate Fermi gas can undergo a BCS phase transition if the interatomic interactions in the gas are attractive @7#. In this phenomenon, the Fermi gas is cooled to near absolute zero, so that all trap levels up to the Fermi energy are filled. Attractive interactions can then cause atoms in the vicinity of the Fermi level to form Cooper pairs, with each pair composed of two quantum correlated atoms behaving as a composite Bose particle. In the BCS theory, these bosons automatically undergo BEC and form an atomic superfluid, with the quantum pair correlation of the Cooper pairs characterizing the superfluid properties of the gas. In this paper, we address the question of how to detect this superfluid state once the transition has occured. A promising experimental system consists of a degenerate gas with atoms in an incoherent mixture of two internal hyperfine states. Such a mixture allows Cooper pairing via an s-wave interaction, and leads to practically attainable BCStransition temperatures when the scattering length a is large and negative. This occurs naturally for 6 Li @8#, or can be obtained in the vicinity of a Feshbach resonance for other atoms @9#. We consider here a trapped 6 Li gas in an incoherent mixture of ground states u1&5uMs51/2, MI51& and u2&5uMs51/2, MI50& @2#. The key to observing the superfluid state is to determine the existence of pair correlations. To achieve this goal, we propose to use off-resonance light scattering and Fourierimaging techniques. A laser beam with amplitude EL , frequency v L , and wave-vector k propagating along the z direction is used to illuminate the gas. We take the light to be linearly polarized and tuned near resonance between the 2 S. ground state and 2 P . excited state. To avoid incoherent heating of the gas due to spontaneous emission, the magnitude of the laser detuning, d5v L2v 0, is assumed to be large compared to the transition linewidth g. In vector quantum-field theory @10‐12#, the atoms in the light field can be described by a four-component atomic field C(r)5c 1u1&1c 2u2& 1c e1ue1&1c e2ue2& with c 6 denoting atoms in the ground-state hyperfine levels u6&, and c e6 in the corresponding excited-state hyperfine levels. For large d, the excited-state components can be adiabatically eliminated, yielding a total atomic polarization operator with positivefrequency part @10# 0.3% topic match

Hsu Journal Not Provided 2003 - 0 citations - Show abstract - Cite Abstract: We study an effective field theory describing cold fermionic atoms near a Feshbach resonance. The theory gives a unique description of the dynamics in the limit that the energy of the Feshbach resonance is tuned to be twice that of the Fermi surface. We show that in this limit the zero temperature superfluid condensate is of order the Fermi energy, and obtain a critical temperature TC ≃ 0.43 TF PACS numbers: 03.75.Ss, 64.60.-i, 74.20.-z Typeset using REVTEX 1 After the successful achievement of Bose-Einstein condensation in ultracold atomic gases, a natural question is whether one can achieve superfluidity in a degenerate fermion gas. Samples of fermionic alkali atoms have already been cooled below their Fermi temperature of several hundreds nano-Kelvin [1], where quantum degeneracy phenomena such as Cooperpairing of atoms are potentially important [2]. It was suggested that the superfluidity gap may be made as large as of order the Fermi energy in the alkali atomic gases [3,4,5], using a Feshbach resonance [6], at which the scattering length becomes very large. For weak coupling, the scattering length away from resonance is usually much smaller than the typical wavelength of fermions near the Fermi surface, |a| ≪ k F and the Cooper pairing gap is then given in terms of scattering length as ∆ ≃ 2EFe , (1) where EF is the Fermi energy and h̄kF = pF is the Fermi momentum. The effective strength of attraction is related to the scattering length as V = 4πh̄an/m, where n is the number density and m is the fermion mass. Therefore, a weakly bound Cooper-pair gap is typically much smaller than the Fermi energy. However, if the scattering of fermions occurs at the Feshbach resonance, whose energy is nearly equal to twice that of the Fermi surface, the effective scattering length becomes quite large and so does the gap. In this paper we analyze this enhancement at the Feshbach resonance in detail. At ultralow temperature, the atomic gas can be described by a Fermi liquid à la Landau, whose (effective) Lagrangian density is given as, suppressing the spin indices, Leff = ψ ( 0.2% topic match

[453] Superradiant scattering of laser light from a Bose-Einstein condensate K. Stam Journal Not Provided 2006 - 3 citations - Show abstract - Cite Abstract: We describe the setup to create a large Bose-Einstein condensate (BEC) containing more than 120 million atoms. In the experiment a thermal beam is slowed by a Zeeman slower and captured in a dark-spot magneto-optical trap (MOT). The sample is subsequently spin polarized in a high magnetic field, before the atoms are loaded in the magnetic trap. Spin polarizing in a high magnetic field results in an increase in the transfer efficiency by a factor of 2 compared to experiments without spin polarizing. In the magnetic trap the cloud is cooled to degeneracy in 50 s by evaporative cooling. This large atom number BEC yields the possibility to enter the hydrodynamic regime by evaporative cooling at a relative low density suppressing the effect of avalanches. The collisional opacity can be tuned from the collisionless regime to a collisional opacity of more than 3 by compressing the trap after condensation. In the collisional opaque regime a significant heating of the cloud at time scales shorter than half of the radial trap period is measured. This is direct proof that the BEC is hydrodynamic. Furthermore a detailed study is presented of superradiant scattering from a BEC. The relation between the depletion of the BEC and the onset of the different side modes as well as the transition from the weak to the strong pulse regime is studied yielding a good insight in the coupling processes between the BEC and the side modes. Finally, a simplified model to describe the time evolution of the process is presented. The model gives a good quantitative description of the fraction of atoms coupled to different side modes, showing that the approximations made in the modeling are valid. Also the atom pair production by superradiant backward-scattering from a Bose-Einstein condensate is investigated. In our experiment the energy in the process is conserved by using a pulse with two frequencies. This makes the process resonant, which gives full control over the number of atoms in the different recoil modes. It is shown that resonant backward-scattering produces strongly correlated side modes in which number squeezing and phase correlation are likely. This makes resonant superradiant backward-scattering a promising candidate for many-particle entanglement. 0.0% topic match
