Many-body dynamical localization in Fock space
Nathan Dupont, Bruno Peaudecerf, David Guéry-Odelin +4
We investigate the emergence of many-body dynamical localization (MBDL) in the Fock space of an interacting two-mode bosonic system subject to periodic driving. Using a mapping to…
Symmetry-Induced Logarithmic Relaxation in the Quantum Kicked Rotor
Julien Hébraud, Floriane Arrouas, Bruno Peaudecerf +6
We study the effect of discrete symmetries on coherent multiple scattering in the quantum kicked rotor. When the initial momentum is set to zero -- as in recent Bose-Einstein conde…
Probing non-ergodicity and symmetry via coherent forward scattering in a shaken rotor
F. Arrouas, J. Hébraud, N. Ombredane +9
The Coherent Backscattering (CBS) peak is a well-known interferential signature of weak localization in disordered or chaotic systems. More recently, a second interference feature…
Kardar-Parisi-Zhang and glassy properties in 2D Anderson localization: eigenstates and wave packets
Noam Izem, Bertrand Georgeot, Jiangbin Gong +2
Despite decades of research, the universal nature of fluctuations in disordered quantum systems remains poorly understood. Here, we present extensive numerical evidence that fluctu…
Coherent backscattering and coherent forward scattering effects in variations of the random quantum kicked rotor
Hugo Thomas, Julien Hébraud, Bertrand Georgeot +3
We investigate coherent multiple scattering effects in the random quantum kicked rotor model. By changing the starting time of the Floquet period, two new classes of models can be…
Critical Dynamics of the Anderson Transition on Small-World Graphs
Weitao Chen, Ignacio García-Mata, Ignacio GarcÃa-Mata +5
The Anderson transition on random graphs draws interest through its resemblance to the many-body localization (MBL) transition with similarly debated properties. In this Letter, we…
