Non-linear Diffusion processes and hydrodynamic cascades in lattice gas models.

ORAL

Abstract

We define and explore lattice models of classical nonlinear diffusion. We find evidence for stretched exponential relaxation of finite momentum modes as predicted analytically by Delacretaz and collaborators. We compute the time-momentum scaling function for the structure factor and also define and study numerically infrared cascades in Fourier space.
