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…
