Critical behavior of three-dimensional Ising spin-glass model

First results of massive Monte Carlo simulations of the d=3 Ising spin-glass with ±J bond distribution, performed on a fast special purpose computer, are presented. A qualitative change in the behavior of the system and best fits for the spin-glass correlation length and relaxation time favor equilibrium phase transition at ${\mathrm{T}}_{\mathrm{c}}$/J≊1.2. .AE
