Report

Laser cooling has been successfully used to achieve quantum degeneracy and Bose-Einstein Condensation (BEC) in various atomic species, as demonstrated in multiple studies [1, 2, 3, 4, 5], with significant advantages over evaporative cooling including higher atom numbers, faster cooling times, and minimal atom loss.

Details:

Direct Achievements of BEC Through Laser Cooling:
- Strontium: Stellmer et al. (2013) demonstrated BEC in strontium atoms using continuous Doppler cooling on a narrow-linewidth transition, achieving condensates of up to 10^5 atoms [1].
- Rubidium-87: Urvoy et al. (2019) presented a method to produce BEC of ^87Rb atoms using Raman cooling in a dipole trap, achieving condensation with 2.5×10^4 atoms at 0.6 μK [2]. Similarly, Hu et al. (2017) achieved BEC with ^87Rb atoms using a 2D optical lattice and Raman sideband cooling [4].
- Machine Learning Optimization: Xu et al. (2023) utilized polarization gradient cooling along with machine learning to optimize parameters, forming a small BEC of ~250 ^87Rb atoms in 40 ms [3]. Vendeiro et al. (2022) also applied machine learning to expedite the BEC formation process by optimizing Raman cooling parameters [21].
Sub-Recoil and Advanced Cooling Techniques:
- Narrow-Line Cooling: Several studies, such as Katori et al. (2000) [11] and Bennetts et al. (2017) [9], have discussed the use of narrow intercombination lines and efficient cooling schemes that approach, but may not directly reach, the quantum degeneracy regime.
- Gray Molasses and Raman Sideband Cooling: Fernandes et al. (2012) and Duarte et al. (2011) have demonstrated advanced sub-Doppler cooling techniques such as gray molasses and Raman sideband cooling, significantly lowering temperatures to enable efficient evaporative cooling for quantum degeneracy [8, 13, 29].
Motivation for Laser Cooling Over Evaporative Cooling:
- Higher Atom Numbers: Laser cooling does not inherently result in atom loss, maintaining higher atom numbers crucial for certain experiments, irreplaceable species, or where atom losses are problematic [14].
- Speed and Efficiency: Laser cooling techniques achieve ultra-cold temperatures much faster than evaporative cooling, minimizing overall experimental cycle times [2, 5].
- Control and Specificity: Laser cooling allows for fine-tuning the cooling process to address specific internal states and manipulate specific atomic populations, leading to highly controlled cooling cycles [19].

Conclusion:

Research confirms that laser cooling can achieve quantum degeneracy and BEC in atomic systems, offering numerous benefits over traditional evaporative cooling methods, including higher initial atom counts, speed, and control. Significant advancements in techniques and the application of machine learning have facilitated these achievements, marking a notable shift in cooling methodologies for reaching ultra-cold quantum states.

[8] 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].

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 76.9% topic match

[17] The gray molasses cooling technique for optimizing the temperature of 39K atoms Edward Gutenberg Iraita Salcedo https://doi.org/10.11606/d.76.2021.tde-05102021-150926 2021 - 0 citations - Show abstract - Cite Abstract: IRAITA SALCEDO, E. G. The gray molasses cooling technique for optimizing the temperature of 39K atoms. 2021. 84p. Dissertation (Master in Science)-Instituto de Física de São Carlos, Universidade de São PauloInstituto de Física de São Carlos, Universidade de São Paulo, São Carlos, 2021. Alkali-metal atoms are the foremost candidates for studies of degenerate quantum gases employing sub-Doppler cooling techniques operating either on the D1 or D2 transition. However, the case of 39K atoms has a narrow excited-state structure of the D2 transition compromising difficulty to achieve below the Doppler limit temperature (TD = ~Γ/2kB = 140μK) by employing conventional cooling techniques such as optical molasses or polarization gradient cooling on this transition. In this work, a sub-Doppler cooling known as Gray molasses operating on the |4S1/2〉 → |4P1/2〉 770nm transition D1 is applied to cool a cloud of 39K atoms to sub-Doppler temperatures, which is an important step to reach the quantum degeneracy of the quantum gases. With this approach we reach temperatures below the Doppler limit around 14.3μK by the formation of dark states using the cooling and repumping lasers detuned to the blue side at the Raman resonance (two-photon) in Λ configuration. Then, we ramp down the intensities of each laser beam, in order to cool the atoms to an ultra-low temperature of 8.62μK, getting closer to the photon recoil limit of (Tr = ~2k2 L/2mkB = 0.4μK). In our results, we present a study of the behaviour of the temperature and the number of atoms by the influence of the relative detuning, and also a particular analysis of the temperature by the influence of the global detuning. In the following, we present the lowest temperature as a function of the final intensities D1 molasses. Finally, we compare the performance of our Gray molasses cloud with other works by using a phase space density analysis. 70.5% topic match

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 29.9% topic match

[57] 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. 8.9% topic match

[76] Peer Review File Manuscript Title: Continuous Bose-Einstein condensation Reviewer Comments & Author Rebuttals No author found Journal Not Provided 2022 - 0 citations - Show abstract - Cite Abstract: The authors report the creation of a continuous Bose-condensed sample of strontium atoms, which constitutes a real milestone in AMO physics. The key ingredients that allow its realization, i.e. a continuous gain mechanism and a continuous supply of ultracold atoms, have been independently investigated both theoretically and experimentally in the last 20 years, and several intermediate steps have been achieved in the authors' group in the last few years. The achievement of this landmark objective is a major result, and importantly it paves the road for intriguing follow-up applications, one for all the CW atom lasers. The authors give a precise and detailed summary of the key advances that one step at a time brought to their present result, each time underlying their meaning and limitations. That is the case of both the Bose-stimulated gain mechanisms and the continuous supply of cold atoms at high phase space density. The long quest undertaken by Schreck and co-workers to overtake the paradigm of time-sequential cooling stages towards ultracold atoms has proven successful, and the continuous BEC has now become a reality. How hot atoms evaporated in an oven continuously end up in the CW BEC is described in an exemplary way, with a wealth of quantitative details on the intermediate cooling steps atomic flux, temperature, trap specifications. Particularly engaging is the section devoted to the demonstration that not only the BEC exists, but it is also continuous. The condensate lies within a thermal cloud, hence it is not trivial to demonstrate its presence; clear evidence is however reported, in terms of the observed bi-modal distribution and the anisotropic expansion dynamics of the atomic sample. That the BEC lasts indefinitely i.e. the main claim of this article is proven in several ways in order to dispel any possible doubts: the BEC existence is observed for intervals longer than the lifetime of a pure BEC and of the limitation imposed by the vacuum quality; the dynamics of the CW BEC is studied by interrupting and reactivating the BEC loading in key places of the space-sequential cooling, and a quantitative analysis of the losses mechanism. Subtle features, like the non-thermal equilibrium of the CW BEC, are analyzed in depth, with relevant measurements and specific modeling. 6.0% topic match

[132] Towards laser cooling and trapping of unstable caesium atoms Alexandros Giatzoglou Journal Not Provided 2019 - 0 citations - Show abstract - Cite Abstract: The thesis reports on the work I carried out during my PhD to set up and test a new experimental facility at the Accelerator Laboratory of the University of Jyväskylä, Finland. The final aim was the realisation of a facility for cooling and trapping unstable caesium atoms. Ideally, my work can be divided in two phases, and the structure of this thesis mirrors this goal. The first phase of the work led to setting up the off-line, i.e. independent from the accelerator, set-up for laser cooling and trapping at the Accelerator Laboratory in Jyväskylä. This was necessary to test the effectiveness, robustness, and stability of our laser, optical and control systems for creating and fully-characterising a magneto-optical trap (MOT) of stable 133Cs in the harsh and noisy environment of the Accelerator Laboratory. This required dedicated design of the experimental set-up, with requirements and specifications more strict than those of a conventional atomic physics experiment. The second phase led to setting up the complete, on-line experiment, with the atom-trapping chamber being permanently connected to one of the accelerator’s beam lines positioned within the IGISOL-4 facility. Tests and full characterisation of the “on-line” set-up were conducted. This led to the successful production of a MOT from neutralised 133Cs+ produce as a high-energy beam. At full operation, 133Cs is brought from 104 eV to 10−8 eV in around 5 s. Tests with radioactive beams were also performed and preliminary results are discussed in the thesis. Atomic samples were cooled down to 150 μK. This opens avenues for precision spectroscopy of unstable atomic samples and nuclear forensic applications. In the long term, the facility will allow the realisation of an isomeric Bose-Einstein condensate (BEC), constituting an experimental benchmark for the recently proposed theory of collective gamma-ray decay. 1.8% topic match

[161] Laser Cooling and Inelastic Collisions of the Polyatomic Radical SrOH I. Kozyryev Bulletin of the American Physical Society 2019 - 6 citations - Show abstract - Cite Abstract: Polyatomic molecules, while ubiquitous in nature, were generally perceived as too complicated and “unruly” for the majority of quantum physics experiments. However, recent theoretical analyses have pinpointed the multiple advantages of using complex molecules for diverse applications such as the creation of a universal quantum computer, quantum simulation of non-trivial many-body states, and tests of fundamental physical laws. Throughout my dissertation research I focused on extending experimental techniques from atomic physics to complex molecules. The goal of my work was to not only demonstrate new ways to control molecules, but also develop a novel experimental platform for quantum science – complex polyatomic molecules – and provide tools for physicists to conquer new frontiers in physics and chemistry. The main theme of this thesis is the use of laser radiation to control internal and external degrees of freedom for the triatomic radical strontium monohydroxide (SrOH). The research achievements presented here can be primarily divided into the following areas: i) out-of-equilibrium studies of vibrationally inelastic collisions at cryogenic temperatures, ii) demonstration of the radiation pressure force and the direct laser cooling of polyatomic molecules, and iii) the development of concepts for laser cooling of molecules with six and more atoms. For the collisional studies, offdiagonal optical pumping was used to populate excited Sr-O stretching state and the ratio of elastic to vibrational quenching collisions was determined to be ∼ 700. In the laser cooling work, using only laser light, the transverse temperature of the cryogenic buffer-gas beam of SrOH was reduced from 50 mK to below 1 mK, leading to an order of magnitude increase in phase space density of the molecular beam. Additionally, the prospects of using a coherent bichromatic force for optical 0.2% topic match

[180] Numerical modeling of collisional dynamics of Sr in an optical dipole trap M. Yan, ..., and M. Corcoran Journal Not Provided 2011 - 4 citations - Show abstract - Cite Abstract: Studies of quantum gases have been extended to divalent-atom gases including ytterbium (Yb) and alkaline-earth atoms, such as strontium (Sr) used in our experiment. These systems have become topics of many recent theoretical works proposing quantum computing in optical lattices and creation of novel quantum fluids. Particularly, one significant feature of such atoms, the inter-combination transition with extremely narrow natural line width, has attracted increasing theoretical and experimental interest for an optical Feshbach resonance (OFR), which provides a new method to manipulate the interaction between ultracold atoms. We have achieved the quantum degeneracy of several isotopes of Sr, i.e. the BoseEinstein condensates (BEC) of Sr and Sr, as well as the degenerate Fermi gas of Sr. Forced evaporation cooling in an optical dipole trap (ODT), a standard technique for producing degenerate gases, is employed in our experiments. Accordingly, it is necessary to understand the collisional dynamics of trapped untracold atoms in the ODT during the evaporative cooling in order to improve the efficiency of cooling to obtain the quantum degenerate gases. In this work, a numerical model has been developed to describe evaporative cooling in an ODT. It can be used for traps that possess little spatial symmetry and when the ratio of trap depth to sample temperature is relatively small. It is implemented by a MATHEMATICA code, which provides an appropriate expression for the potential formed by the ODT lasers, and calculates important parameters such as trap oscillation frequencies that can be compared to measurements of trap parameters to confirm that we characterize our ODT well. It is important particularly at the end of the forced-evaporative cooling where gravity significantly modifies the potential. Moreover, it also calculates numerical approximations to various statistical mechanical quantities at a given temperature that can be used for efficient numerical calculations of evaporation dynamics. Due to the temperature and ODT laser intensity dependence, these statistical mechanical quantities are evaluated at a series of temperature and laser intensity points, which is used to generate interpolating functions of all quantities instead of time-intensive integral evaluations. Using the interpolating functions, the atom number and temperature evolution can be easily found for a given initial condition from the evolution equations related to all these quantities by employing an ordinary differential equation solver in MATHEMATICA . It is important to note that having interpolating functions for the variation of potential and all quantities calculated from potential with ODT laser intensity allows us to model forced evaporation, since the ODT laser intensity is varied in a known way with time during the evaporation trajectory. Then, ultracold collision properties, e.g. the one-body loss rate, the two-body inelastic collision rate constant, and s-wave scattering length, can be extracted by fitting the curves of calculated evolution of the atom number and temperature to experimental data, which help us understand the atomic physics of ultracold strontium. Alternatively, with the aid of the interpolating functions of statistical mechanical quantities and for a given evaporation trajectory, the model can provide evolution curves of some important parameters, such as the trap depth, and the phase space density, which are crucial for us to characterize the evaporation process and optimize the efficiency of cooling. Here, the main body is a paper published in Physical Review A. Additionally, Appendix B describes the calculation of the inelastic and elastic two-body loss rate constants, and Appendix C is detailed checks of calculations of parameters used in the model against various analytic expressions that are valid in appropriate regimes.

We compare simulation results with experiments on 88Sr and 84Sr, which have well-characterized collisional properties.

[183] A tunable Bose-Einstein condensate for quantum interferometry M. Landini Journal Not Provided 2011 - 2 citations - Show abstract - Cite Abstract: The subject of this thesis is the use of BECs for atom interferometry. The standard way atom interferometry is today performed is by interrogating free falling samples of atoms. The employed samples are cold (but not condensed) to have high coherence, and dilute, not to interact significantly with each other. This technique represents nowadays an almost mature field of research in which the achievable interferometric sensitivity is bounded by the atomic shot noise. Until a few years ago the employment of BECs in such devices was strongly limited by the effect of the interactions between the condensed atoms. This obstacle is today removable exploiting interaction tuning techniques. The use of BECs would be advantageous for atom interferometry inasmuch they represents the matter analogue of the optical laser providing the maximum coherence allowed by quantum mechanics. Moreover, non-linear dynamic can be exploited in order to prepare entangled states of the system. The realization of entangled samples can lead to sub-shot noise sensitivity of the interferometers. At today very nice proof-of-principle experiments have been realized in this direction but a competitive device is still missing. This thesis work is inserted in a long term project whose goal is the realization of such a device. The basic operational idea of the project starts with the preparation of a BEC in a double well potential. By the effect of strong interactions the atomic system can be driven into an entangled state. Once the entangled state is prepared, interactions can be ”switched off” and the interferometric sequence performed. This thesis begins with the description of the apparatus for the production of tunable BECs to be used in the interferometer. We chose to work with 39K atoms because this atomic species presents many convenient Feshabch resonances at easily accessible magnetic field values. The cooling of this particular atomic species presents many difficulties, both for the laser and evaporative cooling processes. For this reason, this was the last alkaline atom to be condensed. Its condensation up to now was only possible by employing sympathetic cooling with another species. In this thesis our solutions to the various cooling issues is reported. In particular we realized sub-Doppler cooling for the first time for this species and we achieved condensation via evaporation in an optical dipole trap taking advantage of a Feshbach resonance. In the last part of this work, are presented original calculations for the effects of thermal fluctuations on the coherence of a BEC in a double well, discussing the interplay between thermal fluctuations and interactions in this system. Estimations and feasibility studies regarding the double well trap to be realized are also reported. 0.0% topic match

[219] Nonlinear behaviour of ultracold atoms in optical dipole traps : large atomic light shifts, a quantum phase transition, and interaction-dependent dynamics S. Coop https://doi.org/10.5821/dissertation-2117-122698 2018 - 0 citations - Show abstract - Cite - PDF Abstract: This thesis reports on theory and results from two experiments related to nonlinear behaviour in ensembles of optically-trapped ultracold atoms. The first experiment, performed at ICFO in Barcelona, regards the prediction and measurement of strong ac Stark shifts (light shifts). We present a numerical method based on Floquet's theorem for calculating light shifts to all orders with fewer approximations than the usual calculation based on second-order perturbation theory. The method is experimentally validated by performing absorption spectroscopy of a optically-trapped cloud of cold 87Rb atoms in three scenarios. 1) The atoms are trapped in a singly-polarised monochromatic dipole trap with a wavelength detuned aprox 30nm from the nearest atomic transition. 2) A bichromatic two-polarisation trap, where one wavelength is much closer to atomic transitions (aprox 0:01nm detuning), and finally 3) Another monochromatic trap but with the wavelength variable and scanned close to atomic transitions, again with aprox 0:01nm detuning but three times the intensity of the near-resonant light in the previous experiment, producing nonlinear light shifts of the D2 transition upto aprox 1 GHz. We discuss the potential application of the method to the accuratemeasurement of electric dipole transition matrix elements. The method is extendedto calculate atomic energy level shifts in the presence of light and staticmagnetic fields. The second experiment was performed at LENS in Florence, and involves 39K atoms with tunable interactions cooled into the ground- and first-excited state of a two-mode optical potential. We derive a diferential equation to describe behaviour of a two-mode quantum system with tunable interactions, and then solve it to model behaviour of the system in the three distinct regimes of attractive, zero, and repulsive interatomic interactions. With attractive interactions the system is shown to exhibit a quantum phase transition, and with repulsive interactions is shown to exhibit nonlinear dynamics, including behaviour analogous to a superconducting Josephson junction. As background material the thesis presents a summary of standard laser cooling and trapping echniques, namely Doppler cooling, o+ o- polarisation gradient cooling, magneto-optical trapping, and optical trapping. Optical traps are discussed in detail. We discuss relevant basic physics, derive and analyse a technique for using light shifts to characterise an optical trap, discuss optical Bose-Einstein condensation and control of light intensity to reduce noise-induced heating. Also described is a theoretical proposal for optical evaporation with a constant-depth trap. Esta tesis describe la investigación teórica y los resultados de dos experimentos relacionados con el comportamiento no lineal en un conjuntos de áatomos ultrafríos atrapados ópticamente. En el primer experimento, realizado en ICFO en Barcelona, se presenta la predicción y unos resultados de fuertes cambios de ac Stark (light shifts). Se explica un método numérico basado en el teorema de Floquet para calcular light shifts a todos órdenes con menos aproximaciones que el método habitualmente usado basado en teoría de perturbaciones de segundo orden. El método se valida experimentalmente mediante la realización de espectroscopía de absorción en una nube de átomos de 87Rb ópticamente atrapados en tres escenarios distintos. En el primero, los átomos están atrapados en una trampa de dipolo monocromática de polarización única con una longitud de onda desintonizada 30nm a la transición atómica más cercana. En el segundo se emplea una trampa bicromática de dos polarizaciones, donde una longitud de onda está mucho más cerca de las transiciones atámicas (0.01nm fuera de resonancia). En el tercer y ultimo escenario, se usa una trampa monocromática con la longitud de onda variable y escaneado cerca de transiciones atómicas, nuevamente con 0.01nm desintonizada pero tres veces más intensa que la luz casi resonante del experimento anterior, produciendo light shifts no lineales de la transición D2 hasta 1 GHz. Se discute la aplicabilidad del método para la medición precisa de los elementos de la matriz de transición dipolar eléctrica. Por último, el método se extiende permitiendo calcular los cambios de niveles de energía atómica en presencia de luz y campos magnéticos estáticos. El segundo experimento que se describe en esta tesis se realizó en LENS, en Florencia, e involucra átomos de 39K con interacciones sintonizables en átomos fríos ocupando al estado fundamental y el primer estado excitado de un potencial óptico de dos modos. Se deriva una ecuación diferencial para describir el comportamiento de un sistema cuántico de dos modos con nteracciones sintonizables. Esta se resuelve para modelar el comportamiento del sistema en tres regímenes distintos de interacciones inter-atómicas: atractivas, nulas y repulsivas. En el caso de interacciones atractivas se muestra que el sistema exhibe una transición de fase cuántica. En presencia de interacciones repulsivas el sistema muestra dinámica no lineal, incluyendo un comportamiento análogo a una unión superconductora de Josephson. Como material de referencia, la tesis presenta un resumen de las técnicas estándar de enfriamiento y atrapamiento láser, concretamente enfriamiento Doppler, enfriamiento por gradiente de polarización, atrapamiento magneto-óptico y atrapamiento óptico. Las trampas ópticas se revisan en detalle. Discutimos la física básica relevante, derivamos y analizamos una técnica para usar los light shift para caracterizar una trampa óptica. Analizamos la condensación óptica de Bose-Einstein y el control de la intensidad de la luz para reducir el calentamiento inducido por el ruido. También se presenta una propuesta teórica para la evaporación óptica con una trampa de profundidad constante. 0.0% topic match
