Thermodynamic potentials for the infinite range Ising model with strong coupling

Hilfer, R. - In: Physica A: Statistical Mechanics and its Applications 320 (2003) C, pp. 429-434

The specific Gibbs free energy has been calculated for the infinite range Ising model with fixed and finite interaction strength. The model shows a temperature driven first-order phase transition that differs from the infinite ranged Ising model with weak coupling. In the temperature-field phase...

The infinite-range two-real-Ising replicas spin glass

Nobre, Fernando D.; Costa, Francisco A. da - In: Physica A: Statistical Mechanics and its Applications 254 (1998) 3, pp. 333-347

A spin-glass model, with two Ising coupled systems (real replicas), is investigated in the limit of infinite-range … interactions, through the replica method. Besides the Ising representation, the model is also considered as a discrete two …
