Abstract
The low temperature dynamics of the three-dimensional Ising spin-glass in zero field with a discrete bond distribution is investigated via MC simulations. The thermoremanent magnetization is found to decay algebraically and the temperature dependent exponents agree very well with the experimentally determined values. The nonequilibrium autocorrelation function C(t, tw) shows a crossover at the waiting (or aging) time tw from algebraic quasiequilibrium decay for times t<>tw with an exponent similar to one for the remanent magnetization.Keywords
