摘      要：We present a detailed Monte Carlo evaluation of the equilibrium distribution of local spin-flip rates and local energies in the paramagnetic phase of the d=2 and d=3±J Ising spin glass. Both quantities are spatially heterogeneous, and we find that the shapes of the distributions change dramatically with decreasing temperature. In particular as temperature decreases we find that for an increasing fraction of spins the local spin-flip rate and local energy increase as the glass transition is approached.
