Resolution of the Two-Dimensional Ferromagnetic Spin-3/2 Ising Model via Cluster Growth
J. Roberto Viana, Octavio D. Rodriguez Salmon, Minos A. Neto +2
We propose a computational methodology based on a hierarchical cluster growth process to solve spin-3/2 Ising models efficiently. The method circumvents the exponential complexity…
Revisiting a variational study of the quantum spin-1/2 Heisenberg antiferromagnet
Kevin J. Urcia Vidarte, Luigui A. Chero Nunura, Octavio D. Rodriguez Salmon +1
The variational study of the ground state of the spin anisotropic Heisenberg antiferromagnet has been revisited on a square lattice by improving and correcting past numerical…
Phase transition induced for external field in tree-dimensional isotropic Heisenberg antiferromagnet
Minos A. Neto, J. Roberto Viana, Octavio D. R. Salmon +2
In this paper, we report mean-field and effective-field renormalization group calculations on the isotropic Heisenberg antiferromagnetic model under a longitudinal magnetic field.…
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 spin-3/2 Blume-Capel model with competing short- and long-range interactions
Octavio D. Rodriguez Salmon, Jose Ricardo de Sousa, Minos A. Neto +3
The phase diagrams of the spin- Blume-Capel model with competing short and long-range interactions were studied through the free energy density obtained by analytical methods.…
The Anisotropic Four-State Clock Model in the Presence of Random Fields
Octavio Daniel Rodriguez Salmon, Fernando Dantas Nobre
A four-state clock ferromagnetic model is studied in the presence of different configurations of anisotropies and random fields. The model is considered in the limit of infinite-ra…
