Space-time statistical solutions for the Hamiltonian field-crystal system
Abstract:
We consider the dynamics of a scalar field coupled to a harmonic crystal with n components in dimension d, d,n≥1. The dynamics of the system is translation-invariant with respect to the discrete subgroup Zd of Rd. We study the Cauchy problem with random initial data. We assume that the initial measure has a finite mean energy density and the initial correlation functions are translation invariant with respect to the subgroup Zd. We prove the convergence of space-time statistical solutions to a Gaussian measure.
