Scalable Hamiltonian learning for large-scale out-of-equilibrium quantum dynamics
Agnes Valenti, Guliuxin Jin, Julian Léonard +2
Large-scale quantum devices provide insights beyond the reach of classical simulations. However, for a reliable and verifiable quantum simulation, the building blocks of the quantu…
Signatures of bath-induced quantum avalanches in a many-body--localized system
Julian Léonard, Sooshin Kim, Matthew Rispoli +6
Strongly correlated systems can exhibit surprising phenomena when brought in a state far from equilibrium. A spectacular example are quantum avalanches, that have been predicted to…
Analyzing non-equilibrium quantum states through snapshots with artificial neural networks
A. Bohrdt, S. Kim, A. Lukin +5
Current quantum simulation experiments are starting to explore non-equilibrium many-body dynamics in previously inaccessible regimes in terms of system sizes and time scales. There…
Fractional Chern insulators of few bosons in a box: Hall plateaus from center-of-mass drifts and density profiles
C. Repellin, J. Léonard, N. Goldman
Realizing strongly-correlated topological phases of ultracold gases is a central goal for ongoing experiments. And while fractional quantum Hall states could soon be implemented in…
Optical transport and manipulation of an ultracold atomic cloud using focus-tunable lenses
Julian Léonard, Moonjoo Lee, Andrea Morales +3
We present an optical setup with focus-tunable lenses to dynamically control the waist and focus position of a laser beam, in which we transport a trapped ultracold cloud of 87-Rb…
Superfluid behaviour of a two-dimensional Bose gas
Rémi Desbuquois, Lauriane Chomaz, Tarik Yefsah +4
Two-dimensional (2D) systems play a special role in many-body physics. Because of thermal fluctuations, they cannot undergo a conventional phase transition associated to the breaki…
Rotationally induced Penning ionization of ultracold photoassociated helium dimers
J. Léonard, A. P. Mosk, M. Walhout +4
We have studied photoassociation of metastable \tripS helium atoms near the \tripS-\tripP asymptote by both ion detection in a magneto-optical trap and trap-loss measurements in a…
