Temperature dependence of spatial and dynamic heterogeneities above the ising spin glass transition

摘要

The temperature dependence of the microstructure and local dynamics in the paramagnetic phase of the d= 2 and d= 3 +-J Ising spin glass model is examined by comparing the equilibrium distributions of local flip-rates and local energies calculated in large-scale Monte Carlo simulations. The emergence in this model of fast processes as the glass transition is approached corresponds with recent experimental results.
