First-order phase transition by a spin-flip potential in BCS superconductivity
Octavio D. Rodriguez Salmon, Igor Tavares Padilha, Francisco Dinóla Neto
A spin-flip potential is introduced in a BCS Hamiltonian in order to study a possible thermodynamic effect that might be caused by the addition of a magnetic impurity in a supe…
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…
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.…
Mechanism for enhancement of superconductivity in multi-band systems with odd parity hybridization
Mucio A. Continentino, Igor T. Padilha, Heron Caldas
The study of multi-band superconductivity is relevant for a variety of systems, from ultra cold atoms with population imbalance to particle physics, and condensed matter. As a cons…
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…
