Chain version of the constant coupling theory with application to classical Heisenberg model

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The version of the constant coupling theory, based on exact solutions of some onedimensional systems is proposed. The theory is applied to classical Heisenberg model. The expressions for the order parameters, internal energy, free energy, entropy and critical temperature are given. A good agreement of the presented results with predictions of high temperature series expansion is obtained.
