Quantum simulation of disordered systems with cold atoms

JC Garreau - Comptes Rendus. Physique, 2017 - comptes-rendus.academie-sciences …
This paper reviews the physics of quantum disorder in relation with a series of experiments
using laser-cooled atoms exposed to “kicks” of a standing wave, realizing a paradigmatic …

Critical dynamics of long-range quantum disordered systems

W Chen, G Lemarié, J Gong - Physical Review E, 2023 - APS
Long-range hoppings in quantum disordered systems are known to yield quantum
multifractality, the features of which can go beyond the characteristic properties associated …

Controlling symmetry and localization with an artificial gauge field in a disordered quantum system

C Hainaut, I Manai, JF Clément, JC Garreau… - Nature …, 2018 - nature.com
Anderson localization, the absence of diffusion in disordered media, draws its origins from
the destructive interference between multiple scattering paths. The localization properties of …

Coherent multiple scattering of out-of-equilibrium interacting Bose gases

N Cherroret, T Scoquart, D Delande - Annals of Physics, 2021 - Elsevier
We review recent theoretical and experimental progresses in the coherent multiple
scattering of weakly interacting disordered Bose gases. These systems have allowed, in the …

Quench dynamics of a weakly interacting disordered Bose gas in momentum space

T Scoquart, T Wellens, D Delande, N Cherroret - Physical Review Research, 2020 - APS
We study theoretically the out-of-equilibrium dynamics in momentum space of a weakly
interacting disordered Bose gas launched with a finite velocity. In the absence of …

Low-energy prethermal phase and crossover to thermalization in nonlinear kicked rotors

M Martinez, PÉ Larré, D Delande, N Cherroret - Physical Review A, 2022 - APS
In the presence of interactions, periodically driven quantum systems generically thermalize
to an infinite-temperature state. Recently, however, it was shown that in random kicked …

Ratchet effect in the quantum kicked rotor and its destruction by dynamical localization

C Hainaut, A Rançon, JF Clément, JC Garreau… - Physical Review A, 2018 - APS
We study experimentally a quantum kicked rotor with broken parity symmetry, supporting a
ratchet effect due to the presence of a classical accelerator mode. We show that the short …

Berezinskii approach to disordered spin systems with asymmetric scattering and application to the quantum boomerang effect

J Janarek, N Cherroret, D Delande - arXiv preprint arXiv:2307.15354, 2023 - arxiv.org
We extend the Berezinskii diagrammatic technique to one-dimensional disordered spin
systems, in which time-reversal invariance is broken due to a spin-orbit coupling term …

Crossover from renormalized to conventional diffusion near the three-dimensional Anderson localization transition for light

LA Cobus, G Maret, A Aubry - Physical Review B, 2022 - APS
We report on anomalous light transport in the strong scattering regime. Using low-coherence
interferometry, we measure the reflection matrix of titanium dioxide powders, revealing …

Observation of the quantum boomerang effect

R Sajjad, JL Tanlimco, H Mas, A Cao… - Physical Review X, 2022 - APS
A particle in an Anderson-localized system, if launched in any direction, should, on average,
return to its starting point and stay there. Despite the central role played by Anderson …
