Phase separation of the Potts model in the square lattice
Abstract
When the two dimensional qcolor Potts model in the square lattice is quenched at zero temperature with Glauber dynamics, the energy decreases in time following an AllenCahn power law, and the system converges to a phase with energy higher than the ground state energy after an arbitrary large time when q>4. At low but finite temperature, it cesses to obey the powerlaw regime and orders after a very long time, which increases with q, and before which it performs a domain growth process which tends to be slower as q increases. We briefly present and comment numerical results on the ordering at nonzero temperature.
