Pair correlation functions of the Ising type model with spin 1 within two-particle cluster approximation

Statistical Mechanics 2019-05-21 v1

Abstract

The Blume-Emery-Griffiths model on hypercubic lattices within the two-particle cluster approximation is investigated. The expressions for the pair correlation functions in k\bf{k}-space are derived. On the basis of obtained results (at k=0\bf{k}=0) the static susceptibility of this model on the simple cubic lattice is calculated at various values of the single-ion anisotropy and biquadratic interaction.
