Off-equilibrium dynamics at very low temperatures in three-dimensional spin glasses

摘要: We present a high-statistic systematic study of the overlap correlation function well below critical temperature in three-dimensional Gaussian spin glass. The off-equilibrium has been studied confirming power law behaviour for dynamical length. In particular, we have computed exponent z wide range temperatures, 0.35 T 0.9, obtaining dependence (T ) = 6.2/T very good agreement with recent experiments. Moreover, report violation fluctuation-dissipation theorem low temperatures 0.5 and 0.35. All our numerical results avoid droplet model interpretation even when is as
