Series Analysis of a Three-state Potts Model with Three-site Interactions

Abstract

Series expansions are used to investigate a three-state Potts model which has two-site interactions on the bonds of a triangular lattice and three-site interactions on alternate triangles. Although some of the exponent estimates show variations with interaction strengths, the assumption of scaling constrains the permitted exponent values to such an extent that the possible variations lie within the ranges of uncertainty of individual exponent estimates.
