Irreversible thermalization vs reversible dynamics mediated by anomalous correlators: Wave turbulence theory and experiments in optical fibers
T. Torres, J. Garnier, L. Zanaglia +8
We theoretically and experimentally investigate spontaneous self-organization in a conservative (Hamiltonian) turbulent wave system, operating far from thermodynamic equilibrium. O…
Spatio-temporal equilibrium thermodynamics of guided optical waves at positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Claire Michel +5
Optical thermalization has been recently studied in the 2D spatial evolution of (quasi-)monochromatic light waves propagating in multimode waveguides. Here, we investigate the spat…
Spatio-temporal thermalization and adiabatic cooling of guided light waves
Lucas Zanaglia, Josselin Garnier, Iacopo Carusotto +3
We propose and theoretically characterize three-dimensional spatio-temporal thermalization of a continuous-wave classical light beam propagating along a multi-mode optical waveguid…
Wave turbulence, thermalization and multimode locking in optical fibers
M. Ferraro, K. Baudin, M. Gervaziev +9
We present a comprehensive overview of recent advances in theory and experiments on complex light propagation phenomena in nonlinear multimode fibers. On the basis of the wave turb…
Stochastic Dynamics of Incoherent Branched Flow
Josselin Garnier, Antonio Picozzi, Theo Torres
Waves propagating through weakly disordered smooth linear media undergo a universal phenomenon called branched flow. Branched flow has been observed and studied experimentally in v…
Surface waves in randomly perturbed discrete models
Josselin Garnier, Basant Lal Sharma
We study the propagation of surface waves across structured surfaces with random, localized inhomogeneities. A discrete analogue of Gurtin-Murdoch model is employed and surface ela…
Bridging Rayleigh-Jeans and Bose-Einstein condensation of a guided fluid of light with positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Sergio Rica +5
We consider the free propagation geometry of a light beam (or fluid of light) in a multimode waveguide. As a result of the effective photon-photon interactions, the photon fluid th…
Scattered wavefield in the stochastic homogenization regime
Josselin Garnier, Laure Giovangigli, Quentin Goepfert +1
In the context of providing a mathematical framework for the propagation of ultrasound waves in a random multiscale medium, we consider the scattering of classical waves (modeled b…
Rayleigh-Jeans thermalization vs beam cleaning in multimode optical fibers
Kilian Baudin, Josselin Garnier, Adrien Fusaro +4
Classical nonlinear waves exhibit, as a general rule, an irreversible process of thermalization toward the Rayleigh-Jeans equilibrium distribution. On the other hand, several recen…
Effective dynamics in lattices with random mass perturbations
Josselin Garnier, Basant Lal Sharma
We consider a one-dimensional mono-atomic lattice with random perturbations of masses spread over a finite number of particles. Assuming Newtonian dynamics and linear nearest-neigh…
