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…
