Journal of Physics C Solid State PhysicsCritical behaviour of the three-state antiferromagnetic Potts model in two dimensionsP ReedPublished Oct 10, 1985• 1 citationPublisherAbstractThe critical properties of the three-state Potts antiferromagnet on a square lattice have been investigated by 'large-cell' renormalisation using an exact numerical technique. The results indicate the existence of a single fixed point at beta -1=0.DOI10.1088/0022-3719/18/28/001
