Interplay of thermalization and strong disorder: Wave turbulence theory, numerical simulations, and experiments in multimode optical fibers

N Berti, K Baudin, A Fusaro, G Millot, A Picozzi… - Physical Review Letters, 2022 - APS
We address the problem of thermalization in the presence of a time-dependent disorder in
the framework of the nonlinear Schrödinger (or Gross-Pitaevskii) equation with a random …

Dramatic acceleration of wave condensation mediated by disorder in multimode fibers

A Fusaro, J Garnier, K Krupa, G Millot, A Picozzi - Physical review letters, 2019 - APS
Classical nonlinear waves exhibit a phenomenon of condensation that results from the
natural irreversible process of thermalization, in analogy with the quantum Bose-Einstein …

Rayleigh–Jeans thermalization vs beam cleaning in multimode optical fibers

K Baudin, J Garnier, A Fusaro, C Michel, K Krupa… - Optics …, 2023 - Elsevier
Classical nonlinear waves exhibit, as a general rule, an irreversible process of
thermalization toward the Rayleigh–Jeans equilibrium distribution. On the other hand …

Optical phase transitions in photonic networks: a spin-system formulation

A Ramos, L Fernández-Alcázar, T Kottos, B Shapiro - Physical Review X, 2020 - APS
We investigate the collective dynamics of nonlinearly interacting modes in multimode
photonic settings. To this end, we have established a connection with the theory of spin …

interacting disordered Bose gas launched with a finite velocity. In the absence of …

Quantum boomerang effect for interacting particles

J Janarek, D Delande, N Cherroret, J Zakrzewski - Physical Review A, 2020 - APS
When a quantum particle is launched with a finite velocity in a disordered potential, it may
surprisingly come back to its initial position at long times and remain there forever. This …

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 …

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 …
