Abstract

 One of the main topics in statistical mechanics is the derivation of equations of fluids from microscopic Hamiltonian dynamics. We consider a family of asymmetric/weakly asymmetric exclusions with different velocities, coupled through binary collisions that conserve the total momentum. Assuming special initial distribution given by a small perturbation on the equilibrium state, a law of large numbers holds for the properly rescaled density-velocity field. Depending on the chosen velocity set, the limit field evolves with different PDEs, including the incompressible Navier-Stokes equations. We will review some important existing results and introduce recent progress on this topic. Based on joint works with Patrick van Meurs, Kenkichi Tsunoda and Linjie Zhao.
