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 …

Coherent backscattering of ultracold atoms

F Jendrzejewski, K Müller, J Richard, A Date… - Physical Review Letters, 2012 - APS
We report on the direct observation of coherent backscattering (CBS) of ultracold atoms in a
quasi-two-dimensional configuration. Launching atoms with a well-defined momentum in a …

Coherent forward scattering peak induced by anderson localization

T Karpiuk, N Cherroret, KL Lee, B Grémaud, CA Müller… - Physical review …, 2012 - APS
Numerical simulations show that, at the onset of Anderson localization, the momentum
distribution of a coherent wave packet launched inside a random potential exhibits, in the …

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 …

Quantum transport of atomic matter waves in anisotropic two-dimensional and three-dimensional disorder

M Piraud, L Pezzé, L Sanchez-Palencia - New Journal of Physics, 2013 - iopscience.iop.org
The macroscopic transport properties in a disordered potential, namely diffusion and
weak/strong localization, closely depend on the microscopic and statistical properties of 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 …

Thermalization of matter waves in speckle potentials

N Cherroret, T Karpiuk, B Gremaud, C Miniatura - Physical Review A, 2015 - APS
We show that the momentum distribution of a nonlinear matter wave suddenly released with
a finite velocity in a speckle potential converges, after an out-of-equilibrium evolution, to a …

Suppression and revival of weak localization through control of time-reversal symmetry

K Müller, J Richard, VV Volchkov, V Denechaud… - Physical review …, 2015 - APS
We report on the observation of suppression and revival of coherent backscattering of
ultracold atoms launched in an optical disorder in a quasi-2D geometry and submitted to a …

Coherent forward scattering as a robust probe of multifractality in critical disordered media

M Martinez, G Lemarié, B Georgeot, C Miniatura… - SciPost Physics, 2023 - scipost.org
We study coherent forward scattering (CFS) in critical disordered systems, whose
eigenstates are multifractals. We give general and simple arguments that make it possible to …

Weakly interacting disordered Bose gases out of equilibrium: From multiple scattering to superfluidity (a)

T Scoquart, PÉ Larré, D Delande… - Europhysics …, 2021 - iopscience.iop.org
We explore the quench dynamics of a two-dimensional, weakly interacting disordered Bose
gas for various relative strengths of interactions and disorder. This allows us to identify two …
