Bureik, Jan-Philipp. « Number statistics and momentum correlations in interacting Bose gases ». Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASP014.
Texte intégralThis thesis work is dedicated to the study of number statistics and momentum correlations in interacting lattice Bose gases. The Bose-Hubbard model is simulated by loading Bose-Einstein condensates (BECs) of metastable Helium-4 atoms into a three-dimensional (3D) optical lattice. This model exhibits a quantum phase transition from a superfluid to a Mott insulator that is driven by interaction-induced quantum fluctuations. The objective of this work is to comprehend the role of these quantum fluctuations by analyzing their signatures in momentum space. The original detection scheme employed towards this aim provides the single-particle resolved momentum distribution of the atoms in 3D. From such datasets made up of thousands of individual atoms, the number statistics of occupation of different sub-volumes of momentum space yield information about correlation or coherence properties of the interacting Bose gas. At close-by momenta these occupation probabilities permit the identification of underlying pure-state statistics in the case of textbook many-body states such as lattice superfluids and Mott insulators. In the weakly-interacting regime, well-established correlations between pairs of atoms at opposite momenta are observed. Furthermore, these pair correlations are found to decrease in favor of more intricate correlations between more than two particles as interactions are increased. A direct observation of non-Gaussian correlations encapsulates the complex statistical nature of strongly-interacting superfluids well before the Mott insulator phase transition. Finally, at the phase transition, fluctuations of the occupation number of the BEC mode are found to be enhanced, constituting a direct signature of the quantum fluctuations driving the transition. System-size independent quantities such as the Binder cumulant are shown to exhibit distinctive sharp features even in a finite-size system, and hold promise for constituting suitable observables for determining universal behavior when measured in a homogeneous system

Texte intégralDoctor of Philosophy
Momentum and heat exchange between the fluids (air, water…) and suspensions of solid particles plays a critical role in power generation, chemical processing plants, pharmaceuticals, in the environment, and many other applications. One of the key components in momentum exchange are the forces felt by the particles in the suspension due to the flow of the fluid around them and the amount of heat the fluid can transfer to or from the particles. The fluid forces and heat transfer depend on many factors, chief among them being the properties of the fluid (density, viscosity, thermal properties) and the properties of the particles in the suspension (size, shape, density, thermal properties, concentration). This introduces a wide range of parameters that have the potential to affect the way the fluid and particles behave and move. Experimental measurements are very difficult and expensive to conduct in these systems and computational modeling can play a key role in characterization. For accuracy, computational models have to have the correct physical laws encoded in the software. The objective of this thesis is to use very high-fidelity computer models to characterize the forces and heat transfer under different conditions to develop general formulas or correlations which can then be used in less expensive computer models. Three basic particle shapes are considered in this study, a sphere, a disk like cylindrical particles, and particles of ellipsoidal shapes. More specifically, Particle Resolved Simulations of flow through suspensions of ellipsoids with aspect ratio of 2.5, 5, 10 and cylinders with aspect ratio of 0.25 are performed. The Reynolds number range covered is [10, 200] for ellipsoids and [10, 300] for cylinders with solid fraction range of [0.1, 0.3]. New fluid drag force correlations are proposed for the ellipsoid and cylinder suspensions, respectively, and heat transfer behavior is also investigated.

Texte intégralWe present experimental and theoretical results on ultracold one-dimensional (1D) Bose gases, trapped at the surface of a micro-structure. A large part of the doctoral work was dedicated to the upgrade of the experimental apparatus: the laser system was replaced and the installation of a new imaging objective of high numerical aperture (0.4) required the modification of the atom chip design and the vacuum system. We then probed second-order correlations in momentum space, using a focussing method which allows us to record the velocity distribution of our gas in a single shot. Our data span the weakly-interacting regime of the 1D Bose gas, going from the ideal Bose gas regime to the quasi-condensate. These measurements revealed bunching in both phases, while in the quasi-condensate off-diagonal negative correlations, a the signature of the absence of long-range order in 1D, were revealed. These experimental results agree well with analytical calculations and exact Quantum Monte Carlo simulations. A second project focussed on the cooling of such 1D gases. Since the samples lie in the ground state of the transverse trap, energy selection to carry out usual evaporative cooling is not possible. An alternative cooling scheme, based on non-selective removal of particles, was proposed and demonstrated by colleagues. These findings are compatible with observations on our setup, similar to theirs. Firstly, we also reached temperatures as low as 10% of the transverse gap in earlier experiments. Secondly, with classical field simulations we demonstrate the robustness of the non-thermal arising from these losses: different modes indeed lose energy at different rates. This agrees with the following observation: depending on the thermometry we use, each probing excitations of different energies, the measured temperatures are different, beyond experimental uncertainty. Finally, we relate this non-thermal state to the integrable nature of the 1D Bose gas

Texte intégralCayla, Hugo. « Measuring the momentum distribution of a lattice gas at the single-atom level ». Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLO005/document.
Texte intégralIn this thesis, we report the demonstration of a detection technique able to probe, with a single-atom sensitivity, the momentum distribution of an ultracold gas loaded inside a 3D optical lattice. We have developed a micro-channel plate detector, able to electronically probe clouds of metastable Helium-4. The gas is detected after a time-of-flight of 325ms, long enough to reach the far-field expansion, where the spatial distribution of the cloud can be mapped to the asymptotic momentum distribution. By putting ourselves in a regime where the lattice filling is close to unity, the atomic collisions in the first instant of the expansion become negligible, so that the asymptotic momentum distribution is equal to the in situ momentum distribution. We experimentally demonstrate this equality, by comparing our far-field measurements with the momentum distribution calculated from the Bose-Hubbard Hamiltonian, thanks to ab initio quantum Monte Carlo simulations. We show a good agreement with the theory over more than 3 orders of magnitude in density. Those simulations are calculated with our experimental parameters, the temperature being the only adjustable variable. We then use this comparison to perform a precise thermometry of the lattice gas, allowing us to explore the superfluid-normal gas transition through a direct measurement of different quantities, like the condensed fraction or the two-particles correlation function
