Projectile motion: the "coming and going" phenomenon
Williams J. M. Ribeiro, J. Ricardo de Sousa
An interesting phenomenon that occurs in projectile motion, the "coming and going", is analyzed considering linear air resistance force. By performing both approximate and numerica…
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.…
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…
Thermodynamic properties of rod-like chains: entropic sampling simulations
Lucas S. Ferreira, Lucas N. Jorge, Alvaro A. Caparica +3
In this work we apply entropic sampling simulations to a three-state model which has exact solutions in the microcanonical and grand-canonical ensembles. We consider chains pla…
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…
Reals-space renormalization group study of the anisotropic antiferromagnetic Heisenberg model on the square lattice
N. S. Branco, J. R. de Sousa
In this work we apply two different real-space renormalization-group (RSRG) approaches to the anisotropic antiferromagnetic spin-1/2 Heisenberg model on the square lattice. Our cal…
