Suppressing Parametric Instabilities in Driven Bosonic Lattices through Multi-tone Control
Robbie Cruickshank, Samuel Lellouch, Marin Bukov +3
Periodically driven quantum systems offer remarkable flexibility in tailoring effective Hamiltonians and synthetic band structures. However, such driving also induces heating and d…
Dynamics of the mean-field interacting quantum kicked rotor
Samuel Lellouch, Adam Rançon, Stephan De Bièvre +2
We study the dynamics of the many-body atomic kicked rotor with interactions at the mean-field level, governed by the Gross-Pitaevskii equation. We show that dynamical localization…
Parametric instabilities in a 2D periodically-driven bosonic system: Beyond the weakly-interacting regime
T. Boulier, J. Maslek, M. Bukov +6
We experimentally investigate the effects of parametric instabilities on the short-time heating process of periodically-driven bosons in 2D optical lattices with a continuous trans…
Parametric instabilities of interacting bosons in periodically-driven 1D optical lattices
K. Wintersperger, M. Bukov, J. Näger +6
Periodically-driven quantum systems are currently explored in view of realizing novel many-body phases of matter. This approach is particularly promising in gases of ultracold atom…
Parametric Instability Rates in Periodically-Driven Band Systems
S. Lellouch, M. Bukov, E. Demler +1
This work analyses the dynamical properties of periodically-driven band models. Focusing on the case of Bose-Einstein condensates, and using a meanfield approach to treat inter-par…
Propagation of collective pair excitations in disordered Bose superfluids
Samuel Lellouch, Lih-King Lim, Laurent Sanchez-Palencia
We study the effect of disorder on the propagation of collective excitations in a disordered Bose superfluid. We incorporate local density depletion induced by strong disorder at t…
Localization transition in weakly-interacting Bose superfluids in one-dimensional quasiperdiodic lattices
Samuel Lellouch, Laurent Sanchez-Palencia
We study the localization of collective pair excitations in weakly-interacting Bose superfluids in one-dimensional quasiperiodic lattices. The localization diagram is first determi…
Two-component Bose gases with one-body and two-body couplings
Samuel Lellouch, Tung-Lam Dao, Thomas Koffel +1
We study the competition between one-body and two-body couplings in weakly-interacting two-component Bose gases, in particular as regards field correlations. We derive the meanfiel…
