Séminaire Analyse-Proba (Kohei Hayashi, mardi 12 mai 2026)

Le prochain séminaire Analyse-Proba aura lieu mardi 12 mai à 10h30 en A711. Kohei Hayashi (Osaka University) nous parlera de :

Fluctuating hydrodynamics for a chain of nonlinear stochastic oscillators 

Abstract
We study macroscopic behavior of a chain of oscillators perturbed by some random noise, which admits three conservation laws. Particularly, we assume that the Hamiltonian dynamics of the oscillators is governed by a nonlinear potential that weakly perturbs the purely harmonic one. As a main result, we show that fluctuations of two phonon modes converge to the stochastic Burgers equations.
