Dynamical Simulation of the Heisenberg Spin Glass in Three Dimensions

Abstract

An efficient method of simulating the Heisenberg model is proposed taking into account the spin dynamics, and applied to a short-range Heisenberg spin glass on a simple cubic lattice. Our method shows a drastic reduction in relaxation times and clearly reveals the vanishing of the order parameter q and the divergence of the susceptibility according to the Curie law as the temperature is decreased.
