General approach to the critical phase with coupled quasiperiodic chains

X Lin, X Chen, GC Guo, M Gong - Physical Review B, 2023 - APS
In disordered systems, wave functions in the Schrödinger equation may exhibit a transition
from the extended phase to the localized phase, in which the states at the boundaries or …

Anderson mobility gap probed by dynamic coherent backscattering

LA Cobus, SE Skipetrov, A Aubry, BA Van Tiggelen… - Physical Review Letters, 2016 - APS
We use dynamic coherent backscattering to study one of the Anderson mobility gaps in the
vibrational spectrum of strongly disordered three-dimensional mesoglasses. Comparison of …

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 …

Spatio-temporal imaging of light transport in highly scattering media under white light illumination

A Badon, D Li, G Lerosey, A Claude Boccara, M Fink… - Optica, 2016 - opg.optica.org
Imaging the propagation of light in time and space is crucial in optics, notably for the study of
complex media. We demonstrate the passive measurement of time-dependent Green's …

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 …

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 …

Multifractality of the kicked rotor at the critical point of the Anderson transition

P Akridas-Morel, N Cherroret, D Delande - Physical Review A, 2019 - APS
We show that quantum wave packets exhibit a sharp macroscopic peak as they spread in
the vicinity of the critical point of the Anderson transition. The peak gives a direct access to …

Coherent forward scattering peak and multifractality

M Martinez, G Lemarié, B Georgeot, C Miniatura… - Physical Review …, 2021 - APS
It has recently been shown that interference effects in disordered systems give rise to two
nontrivial structures: the coherent backscattering (CBS) peak, a well-known signature of …

Prethermalization and wave condensation in a nonlinear disordered Floquet system

P Haldar, S Mu, B Georgeot, J Gong… - arXiv preprint arXiv …, 2021 - arxiv.org
Periodically-driven quantum systems make it possible to reach stationary states with new
emerging properties. However, this process is notoriously difficult in the presence of …
