We propose a rigorous definitionof approximate symmetry and of its spontaneous breakdown in connection with a phase transition. We show that this definition is of interest in the case of the Ising model with a small three-spin potential perturbation

Abstract
We propose a rigorous definitionof approximate symmetry and of its spontaneous breakdown in connection with a phase transition. We show that this definition is of interest in the case of the Ising model with a small three-spin potential perturbationFile allegati a questo prodotto
