Free energy variational approach for the classical anisotropic XY model in a crystal field
L. M. Castro, A. S. T. Pires, J. A. Plascak
A variational approach for the free energy is used to study the three-dimensional anisotropic XY model in the presence of a crystal field. The magnetization and the phase diagrams…

Critical behavior of the spin-3/2 Blume-Capel model on a random two-dimensional lattice
F. W. S. Lima, J. A. Plascak
We investigate the critical properties of the spin-3/2 Blume-Capel model in two dimensions on a random lattice with quenched connectivity disorder. The disordered system is simulat…
