Monte Carlo Simulation of the Three-Dimensional Ising Spin Glass
We study the 3D Ed wards-Anderson model with binary interactions by Monte Carlo simulations. Direct evidence of finite–size scaling is provided, and the universal finite–size scaling functions are determined. Using an Iterative extrapolation procedure, Monte Carlo data are extrapolated to infinite volume up to correlation length £ ≈ 140. The infinite volume data are consistent with both a continuous phase transition at finite temperature and an essential singularity at finite temperature. An essential singularity at zero temperature is excluded.
