J. Salas et Ad. Sokal, THE 3-STATE SQUARE-LATTICE POTTS ANTIFERROMAGNET AT ZERO-TEMPERATURE, Journal of statistical physics, 92(5-6), 1998, pp. 729-753
We study the 3-state square-lattice Potts antiferromagnet at zero temp
erature by a Monte Carlo simulation using the Wang-Swendsen-Kotecky cl
uster algorithm, on lattices up to 1024 x 1024. We confirm the critica
l exponents predicted by Burton and Henley based on the height represe
ntation of this model.
