Fourier law from Gaussian closure of Hamiltonian dynamics
We consider a Hamiltonian system of a lattice of coupled anharmonic oscillators driven by stochastic forcing on the boundary. We perform a Gaussian closure for the equations satisfied by the correlation functions of the stationary state of the system and derive Fourier’s law for heat conduction from the closed equations.
