Outofequilibrium dynamics are a characteristic feature of the longtime behavior of nonlinear dispersive equations on bounded domains. This is partly due to the fact that dispersion does not translate into decay in this setting (in contrast to the case of unbounded domains like $R^d$). In this talk, we will take the cubic nonlinear Schroedinger equation as our model, and discuss some aspects of its outofequilibrium dynamics, from energy cascades (i.e. migration of energy from low to high frequencies) to weak turbulence.
