Fisher zeros and Potts zeros of the Q-state Potts model for nonzero external magnetic field
arXiv:cond-mat/0307010
Abstract
The properties of the partition function zeros in the complex temperature plane (Fisher zeros) and in the complex plane (Potts zeros) are investigated for the -state Potts model in an arbitrary nonzero external magnetic field , using the exact partition function of the one-dimensional model.
