Nonlinear diffusion and hydrodynamic fluctuations in kinetically constrained models.

ORAL

Abstract

We study particle diffusion in interacting lattice gas models with kinetic constraints chosen to enhance density dependence of the diffusion process. We document nonlinear diffusion and hydrodynamic long-time tails and explore the "diffusion cascade" recently discussed by L. Delacretaz.
