Abstract

A linked-cluster type of series expansion of the free energy with a variational parameter is developed to the eighth order for the q-state Potts model. The order parameter and the internal energy are then derived. By analyzing these series expansions, critical temperatures Tc, latent heats, and discontinuities of the order parameters at Tc are determined for the cubic lattices.
