Phase transitions in generalized chiral or Stiefel's models

Statistical Mechanics 2015-06-24 v1

Abstract

We study the phase transition in generalized chiral or Stiefel's models using Monte Carlo simulations. These models are characterized by a breakdown of symmetry O(N)/O(N-P). We show that the phase transition is clearly first order for N >= 3 when P=N and P=N-1, contrary to predictions based on the Renormalization Group in 4-\epsilon expansion but in agreement with a recent non perturbative Renormalization Group approach.
