Phase transition temperature in some lattice models

Abstract

A method for calculating the phase transition temperature using only one cell is considered. This method has been tested for various lattice models: Ising model on triangular, hexagonal and tetrahedral lattices, three-position Potts model on a square lattice. In particular, exact reply is reproduced in the Ising model for triangular lattice. Also, this method was used to analyze some multi-spin models.
