Nonequilibrium study of the Ising model with random couplings in the square lattice
Octavio D. Rodriguez Salmon, Minos A. Neto, Thiago Lobo +1
We studied the critical behavior of the spin-{1/2} Ising model in the square lattice by considering fixed and as random interactions following discret…
Ferromagnetic phases due to competing short- and long-range interactions in the spin-S Blume-Capel model
Octavio Daniel Rodriguez Salmon, Minos Adão Neto, Francisco Dinóla Neto +2
We broaden the study of the statistical physics of the spin- Blume-Capel model with ferromagnetic mean-field interactions in competition with short-range antiferromagnetic i…
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…
Cooper-pair size and binding energy for unconventional superconducting systems
Francisco Dinola Neto, Minos A. Neto, Octavio D. Rodriguez Salmon
The main proposal of this paper is to analyze the size of the Cooper pairs composed by unbalanced mass fermions from different electronic bands along the BCS-BEC crossover and stud…
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…
Multicritical behavior of the two-dimensional transverse Ising metamagnet in a longitudinal magnetic field
Denise A. do Nascimento, Josefa T. Pacobahyba, Minos A. Neto +2
Magnetic phenomena of the superantiferromagnetic Ising model in both uniform longitudinal () and transverse () magnetic fields are studied by employing a mean-field variation…
Multicritical Behavior of Two Coupled Ising Models in the Presence of a Random Field
Octavio D. Rodriguez Salmon, Fernando Dantas Nobre
A system defined by two coupled Ising models, with a bimodal random field acting in one of them, is investigated. The interactions among variables of each Ising system are infinite…
Diamagnetic susceptibility of spin-triplet ferromagnetic superconductors
H. Belich, Octavio D. Rodriguez Salmon, Diana V. Shopova +1
We calculate the diamagnetic susceptibility in zero external magnetic field above the phase transition from ferromagnetic phase to phase of coexistence of ferromagnetic order and u…
Multicriticality in the Blume-Capel model under a continuous-field probability distribution
Octavio D. Rodriguez Salmon, Justo Rojas Tapia
The multicritical behavior of the Blume-Capel model with infinite-range interactions is investigated by introducing quenched disorder in the crystal field , which is represe…
