Résumé :
I will consider non-equilibrium dynamics in the classical integrable systems. Integrability techniques allow finding the exact form of the large time asymptotic profile, which I will present as an analog of the Eigenstate State Thermalization Hypothesis. My main examples will be relaxation dynamics in one-dimensional Bose gases, formulated as an initial value problem for the classical nonlinear Schrodinger equation and domain wall "melting " in XXZ magnetic. In the latter case, I show a quantitative agreement with quantum results.
