Denholm, J. and S. Redner

We investigate the long-time relaxation of the q-state kinetic Potts ferromagnet on the triangular lattice that is quenched to zero temperature from a random or an antiferromagnetic initial state. For q = 3, the final state is either the ground state (probability ≈ 0.75), a two-stripe state (probability ≈ 0.09), or a three-hexagon state (probability ≈ 0.16). The relaxation to the hexagonal state is governed by a time that scales as L2 ln L. We provide a heuristic argument for this anomalous scaling and present additional new features of Potts coarsening on the triangular lattice for q = 3 and for q > 3.
