Abstract
The initial-boundary value problem for an infinite one-dimensional chain of harmonic oscillators on the half-line is considered. The large time asymptotic behavior of solutions is studied. The initial data of the system are supposed to be a random function which has some mixing properties. We study the distribution of the random solution at time moments . The main result is the convergence of to a Gaussian probability measure as . We find stationary states in which there is a non-zero energy current at origin.
