- Description
- The three-state antiferromagnetic Potts model on a family of bipartite diamond hierarchical lattices is investigated. We prove that the correlations have a power law and that the order parameter vanishes in the entire low-temperature phase as predicted by Berker and Kadanoff. The internal energy, specific heat and entropy as functions of temperature are also exactly calculated. It is shown that the local order parameter has two distinct multifractal structures one at the critical point and another at the unusual phase.
