Correlation identities and rigorous upper bounds on the critical temperature for the spin-1 Blume–Capel model on a Kagome lattice

Santos, Jander P.; Sá Barreto, F.C. - In: Physica A: Statistical Mechanics and its Applications 421 (2015) C, pp. 548-561

Spin correlation identities for the Blume–Capel model on Kagome lattice are derived and combined with rigorous correlation inequalities lead to upper bounds on the critical temperature. From the spin correlation identities the mean field approximation and the effective field approximation...

Effects of random-crystal-field on the kinetic Blume Capel model

El Yadari, M.; Benayad, M.R.; Benyoussef, A.; El Kenz, A. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4677-4687

The effects of random crystal field on the stationary states of the kinetic spin-1 Blume Capel model are studied using the Glauber-type stochastic dynamics under the time-dependent oscillating field assumption. Our investigation, based on the equilibrium ground state phase diagram, revealed many...

Percolation properties of the antiferromagnetic Blume–Capel model in the presence of a magnetic field

Pawłowski, G. - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 7, pp. 1111-1119

The problem of order–order and order–disorder transitions in the system described by the 2D antiferromagnetic Blume–Capel model in the presence of a magnetic field is studied by the Wang and Landau flat-histogram simulation method and by the classical Monte Carlo. Anomalous thermodynamic...

Critical behavior and phase diagrams of a spin-1 Blume–Capel model with random crystal field interactions: An effective field theory analysis

Yüksel, Yusuf; Akıncı, Ümit; Polat, Hamza - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 9, pp. 2819-2832

A spin-1 Blume–Capel model with dilute and random crystal fields is examined for honeycomb and square lattices by introducing an effective-field approximation that takes into account the correlations between different spins that emerge when expanding the identities. For dilute crystal fields,...

Expanded Bethe–Peierls approximation for the Blume–Capel model

Du, A.; Yü, Y.Q.; Liu, H.J. - In: Physica A: Statistical Mechanics and its Applications 320 (2003) C, pp. 387-397

We have studied the Blume–Capel model by using the expanded Bethe–Peierls approximation. In this approximation, the system is taken as a group of chains composed of a central chain and its nearest-neighbor chains. The nearest-neighbor chains are in an effective field produced by the other...

Correlations equalities and some upper bounds for the critical temperature for spin one systems

Sá Barreto, F.C.; Mota, A.L. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 23, pp. 5908-5917

Starting from correlation identities for the Blume–Capel spin 1 systems and using correlation inequalities, we obtain rigorous upper bounds for the critical temperature. The obtained results improve over effective field type results.
