General approach to the critical phase with coupled quasiperiodic chains
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 …

Coherent forward scattering as a robust probe of multifractality in critical disordered media
We study coherent forward scattering (CFS) in critical disordered systems, whose

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