Abstract

We investigate the relationship between bulk and local relaxation in the Ising spin glass (in 2 and 3 dimensions) for temperatures above but approaching the glass transition temperature, using Monte Carlo computer simulations. We find that the stretched exponential form of the bulk spin autocorrelation function results from a spatial average over a broad range of behavior--from strongly non-exponential to nearly exponential--for the local autocorrelation functions. The spatial correlation of single-site relaxation times obtained from these functions provides a length scale for dynamical heterogeneity which grows with decreasing temperature.
