Revisiting the machine-learning density functional for the one-dimensional Hubbard model with random external potential
Octavio D. R. Salmon, Minos A. Neto, J. Roberto Viana +1
We revisit the machine-learning (ML) approach to the universal density functional of the one-dimensional Hubbard model with a site-dependent random potential $\math…
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…
Saturation Field as a Direct Probe of Exchange and Single-Ion Anisotropies in Spin-1 Magnets
M. A. R. Griffith, S. Rufo, H. Caldas +3
High magnetic fields provide a direct route to probe the anisotropies that govern spin dynamics in layered magnets. Using the SU(3) bond operator framework for spin 1 systems, we d…
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 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 magnetic susceptibility on the transverse antiferromagnetic Ising model: Analysis of the reentrant behaviour
Minos A. Neto, J. Ricardo de Sousa, Igor T. Padilha +3
We study the three-dimensional antiferromagnetic Ising model in both uniform longitudinal () and transverse () magnetic fields by using the effective-field theory with finite…
Qualitative aspects of the phase diagram of J1-J2 model on the cubic lattice
Octavio D. R. Salmon, Nuno Crokidakis, Minos A. Neto +3
The qualitative aspects of the phase diagram of the Ising model on the cubic lattice, with ferromagnetic nearest-neighbor interactions () and antiferromagnetic next-nearest-…
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…
