Effects of ground-state degeneracy on the±Jspin glass

We perform Monte Carlo simulations of the Ising spin glass at low temperature in three dimensions with a +/-J distribution of couplings. Our results display crossover scaling between T=0 behavior, where the order parameter distribution P(q) becomes trivial for L -> ∞, and finite-T behavior, where the non-trivial part of P(q) has a much weaker dependence on the size L, and is possibly size independent.
