Approximate method of free energy calculation for spin system with arbitrary connection matrix

Disordered Systems and Neural Networks 2015-06-23 v1

Abstract

The proposed method of the free energy calculation is based on the approximation of the energy distribution in the microcanonical ensemble by the Gaussian distribution. We hope that our approach will be effective for the systems with long-range interaction, where large coordination number q ensures the correctness of the central limit theorem application. However, the method provides good results also for systems with short-range interaction when the number q is not so large.
