Metastable and unstable states of the Blume–Capel model obtained by the cluster variation method and the path probability method

Ekiz, Cesur; Keskin, Mustafa; Yalçın, Orhan - In: Physica A: Statistical Mechanics and its Applications 293 (2001) 1, pp. 215-232

We investigate the temperature dependence of the order parameters of the Blume–Capel model for zero magnetic field in the lowest approximation of the cluster variation method which is identical to the mean-field approximation. Besides the stable branches of the order parameters, we establish...
