NONEQUILIBRIUM DYNAMICS IN THE RANDOM BOND ISING CHAIN - A REMINISCENCE OF AGING IN SPIN-GLASSES

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 tempera tures a typical (interrupted) aging scenario is established as in two- and similar to three-dimensional spin glass models. Since the underlyi ng mechanism is a slow domain-growth we study in detail spatial correl ations and the time-dependence of the domain- as well as kink-statisti cs. We find that all correlation functions in time and in space as wel l as the domain-size probability distribution function obey simple sca ling laws.
