Abstract

The physical phenomenon of phase transition is reflected in mathematical model by non-uniqueness of the Gibbs measures and phase diagram of the model describes a morphology of phases, stability of phases, different transitions from one phase to another and corresponding transition lines. We study the phase diagram for the Potts model on a Cayley tree with nearest-neighbor interaction J in the presence of an external magnetic field h. To perform this study,an iterative scheme similar to that appearing in real space renormalization group frameworks is established. The phase diagram is fully determined in the T/J −h/J space for all values and signs of J and h. This phase diagram explicitly demonstrates relations between parameters J, h and T, where as in previous works of Peruggi et al such relations were implicit.
