On the approach to equilibrium of an Hamiltonian chain of anharmonic oscillators
Giorgio Parisi
Abstract
In this note we study the approach to equilibrium of a chain of anharmonic oscillators. We find indications that a sufficiently large system always relaxes to the usual equilibrium distribution. There is no sign of an ergodicity threshold. The time however to arrive to equilibrium diverges when g 0, g being the anharmonicity.
