We consider the ±J Ising model on a cubic lattice with a gauge-invariant disorder distribution. Disorder depends on a parameter βG that plays the role of a chemical potential for the amount of frustration. We study the model at a specific value of the disorder parameter β G, where frustration shows longrange correlations. We characterize the universality class, obtaining accurate estimates of the critical exponents: v = 0.655(15) and ηq = 1.05(5), where ηq is the overlap susceptibility exponent.

Abstract
We consider the ±J Ising model on a cubic lattice with a gauge-invariant disorder distribution. Disorder depends on a parameter βG that plays the role of a chemical potential for the amount of frustration. We study the model at a specific value of the disorder parameter β G, where frustration shows longrange correlations. We characterize the universality class, obtaining accurate estimates of the critical exponents: v = 0.655(15) and ηq = 1.05(5), where ηq is the overlap susceptibility exponent.| File | Dimensione | Formato | |
