Abstract
We consider the Ising model on a cubic lattice with a gauge-invariant disorder distribution. Disorder depends on a parameter 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 , where frustration shows long-range correlations. We characterize the universality class, obtaining accurate estimates of the critical exponents: and , where is the overlap susceptibility exponent.
