摘要：
A bivariate multicanonical Monte Carlo simulation of the three-dimensional +/-J Ising spin glass is described. The correlation time of the Monte Carlo dynamics is approximately proportional to the system size, which is a great improvement over previous spin-glass simulations. The order-parameter distribution function P(q) at T = 0.3 exhibits a feature of the droplet picture of the low-temperature phase, as opposed to the mean-field picture.
