The dynamic critical exponent of the q=3 and 4 state Potts model

Abstract

The dynamic Monte Carlo renormalisation group method introduced by Jan, Moseley and Stauffer (1983) is used to determine the dynamic critical exponent, z, for the q=3 and q=4 state Potts model in two dimensions. The authors find that z=2.43+or-0.15 and 2.36+or-0.20 for the q=3 and q=4 state Potts models. These results are in disagreement with the recent conjecture of Domany (1984).
