Quantum kicked rotor and its variants: Chaos, localization and beyond
Kicked rotor is a paradigmatic model for classical and quantum chaos in time-dependent
Hamiltonian systems. More than fifty years since the introduction of this model, there is an …

Engineering a flux-dependent mobility edge in disordered zigzag chains
There has been great interest in experimental studies of charged particles in artificial gauge
fields. Here, we perform the first cold-atom explorations of the combination of artificial gauge …

Anderson localization in dissipative lattices
S Longhi - Annalen der Physik, 2023 - Wiley Online Library
Anderson localization predicts that wave spreading in disordered lattices can come to a
complete halt, providing a universal mechanism for dynamical localization. In the one …

Phase modulation of directed transport, energy diffusion, and quantum scrambling in a Floquet non-Hermitian system
WL Zhao, G Li, J Liu - Physical Review Research, 2024 - APS
We investigate both analytically and numerically the wavepacket's dynamics in momentum
space for a Floquet non-Hermitian system with a periodically kicked driven potential. We …

Dynamics of the mean-field-interacting quantum kicked rotor
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 …

Coherent multiple scattering of out-of-equilibrium interacting Bose gases
We review recent theoretical and experimental progresses in the coherent multiple
scattering of weakly interacting disordered Bose gases. These systems have allowed, in the …

Different effective Hamiltonians in a periodic-driven Bose-Josephson junction
The bosonic Josephson junction, one of the maximally simple models for periodic-driven
many-body systems, has been intensively studied in the past two decades. Here, we revisit …

Effective thermalization of a many-body dynamically localized Bose gas
V Vuatelet, A Rançon - Physical Review A, 2021 - APS
Dynamical localization is the analog of Anderson localization in momentum space, where
the system's energy saturates and the single-particle wave functions are exponentially …

Coherence and decoherence in the Harper-Hofstadter model
We quantum simulated the 2D Harper-Hofstadter (HH) lattice model in a highly elongated
tube geometry—three sites in circumference—using an atomic Bose-Einstein condensate. In …
