Relaxation in classical integrable systems
I will consider non-equilibrium dynamics in the classicalintegrable systems. Integrability techniques allow finding the exactform of the large time asymptotic profile, which I will present as ananalog of the Eigenstate State Thermalization Hypothesis. My mainexamples will be relaxation dynamics in one-dimensional Bose gases,formulated as an initial value problem for the classical nonlinearSchrodinger equation and domain wall "melting " in XXZ magnetic. Inthe latter case, I show a quantitative agreement with quantum results.
