Nonlinear fluctuating hydrodynamics and time-correlations for one-dimensional systems

Our focus are non-integrable classical systems in one dimension, like
Fermi-Pasta-Ulam chains, the discrete nonlinear Schroedinger equation,
and 1D fluids interacting through a short range potential. Nonlinear
fluctuating dynamics is used to compute and predict their
time-correlations in thermal equilibrium.We will explain the connection
to the multi-component Kardar-Parisi-Zhang equation.
