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-…
Phase diagrams of the transverse Ising antiferromagnet in the presence of the longitudinal magnetic field
Minos A. Neto, J. Ricardo de Sousa
In this paper we study the critical behavior of the two-dimensional antiferromagnetic Ising model in both uniform longitudinal () and transverse () magnetic fields. Using the…
The quantum J_{1}-J_{1'}-J_{2} spin-1/2 Heisenberg antiferromagnet: A variational method study
Orlando D. Mabelini, Octavio Salmon, J. Ricardo de Sousa
The phase transition of the quantum spin-1/2 frustrated Heisenberg antiferroferromagnet on an anisotropic square lattice is studied by using a variational treatment. The model is d…
