Universality in phase boundary slopes for spin glasses on self-dual lattices
Universality in phase boundary slopes for spin glasses on self-dual lattices
We study the effects of disorder on the slope of the disorder--temperature phase boundary near the Onsager point (Tc = 2.269...) in spin-glass models. So far, studies have focused on marginal or irrelevant cases of disorder. Using duality arguments, as well as exact Pfaffian techniques we reproduce these analytical estimates. …
