A new effective-field technique for the ferromagnetic spin-1 Blume-Capel model in a transverse crystal field
J. Roberto Viana, Octavio D. Rodriguez Salmon, Minos A. Neto +1
A new approximating technique is developed so as to study the quantum ferromagnetic spin-1 Blume-Capel model in the presence of a transverse crystal field in the square lattice. Ou…

A mean-field approach applied for the ferromagnetic spin-1 Blume-Capel model
J. Roberto Viana, Octavio D. Rodriguez Salmon, Minos A. Neto
We applied a mean-field approach associated to Monte Carlo simulations in order to study the spin-1 ferromagnetic Blume-Capel model in the square and the linear lattice. This new t…

The Ising antiferromagnet on an anisotropic simple cubic lattice in the presence of a magnetic field
Octavio D. R. Salmon, Minos A. Neto, J. Roberto Viana +2
We have studied the anisotropic three-dimensional nearest-neighbor Ising model with competitive interactions in an uniform longitudinal magnetic field . The model consists of fe…
