摘要: The low temperature dynamics of the three dimensional Ising spin glass in zero field with a discrete bond distribution is investigated via MC simulations. thermoremanent magnetization found to decay algebraically and dependent exponents agree very well experimentally determined values. nonequilibrium autocorrelation function $C(t,t_w)$ shows crossover at waiting (or {\em aging}) time $t_w$ from algebraic quasi-equilibrium} for times $t$$\ll$$t_w$ another, faster $t$$\gg$$t_w$ an exponent similar one remanent magnetization.
