A universal amplitude ratio for the q<4 Potts model from a solvable lattice model

Abstract

The universal amplitude ratio $R_{\xi }$ for the ($q⩽4$)-state Potts model in two dimensions is determined by using results for the dilute A model in regime 1. The nature of the relationship between the Potts model and the dilute A model, both related to ${\varphi }_{2,1}$ perturbed conformal field theory, is discussed.
