The 3-State Potts Antiferromagnet on the Hexagonal Lattice

Abstract

We study the 3-state hexagonal-lattice Potts antiferromagnet by a Monte Carlo simulation using the Wang-Swendsen-Kotecky cluster algorithm. We study the staggered susceptibility and the correlation length, and we confirm that this model is disordered at all temperatures T>=0. We also measure the ground-state entropy density.
