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 …

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 …

High-resolution real-space evaluation of the self-energy operator of disordered lattices: Gade singularity, spin–orbit effects and p-wave superconductivity

SM João, JMVP Lopes, A Ferreira - Journal of Physics: Materials, 2022 - iopscience.iop.org
Disorder is a key factor influencing the behavior of condensed states of matter, however the
true extent of its impact is generally difficult to determine due to the prominent roles played …

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 …

Coherent forward scattering as a signature of Anderson metal-insulator transitions

S Ghosh, C Miniatura, N Cherroret, D Delande - Physical Review A, 2017 - APS
We show that the coherent forward scattering (CFS) interference peak amplitude sharply
jumps from zero to a finite value upon crossing a metal-insulator transition. Extensive …

Coherent backscattering reveals the Anderson transition

S Ghosh, D Delande, C Miniatura, N Cherroret - Physical Review Letters, 2015 - APS
We develop an accurate finite-time scaling analysis of the angular width of the coherent
backscattering (CBS) peak for waves propagating in 3D random media. Applying this …
