Color symmetry breaking in the Potts spin glass

Probability 2025-03-12 v2 Disordered Systems and Neural Networks

Abstract

The Potts spin glass is an analogue of the Sherrington-Kirkpatrick model in which each spin can take one of κ\kappa possible values, which we interpret as colors. It was suggested in arXiv:2310.06745 that the order parameter for this model is always invariant with respect to permutations of the colors. We show here that this is false whenever κ58\kappa \ge 58.
