Non-equilibrium dynamics in the random bond Ising chain: A reminiscence of aging in spin glasses

Abstract

Results of extensive Monte-Carlo simulations that investigate the out-of-equilibrium dynamics of the one-dimensional Ising spin glass model with a Gaussian bond-distribution are presented. At low enough temperatures a typical (interrupted) aging scenario is established as in two- and similar to three-dimensional spin glass models. Since the underlying mechanism is a slow domain-growth we study in detail spatial correlations and the time-dependence of the domain- as well as kink-statistics. We find that all correlation functions in time and in space as well as the domain-size probability distribution function obey simple scaling laws.
