Vortex behavior near a spin vacancy in 2D XY-magnets
A. R. Pereira, L. A. S. Mol, S. A. Leonel +2
The dynamical behavior of anisotropic two dimensional Heisenberg models is still a matter of controversy. The existence of a central peak at all temperatures and a rich structure o…
Monte Carlo study of the critical temperature for the planar rotator model with nonmagnetic impurities
S. A. Leonel, Pablo Zimmermann Coura, A. R. Pereira +2
We performed Monte Carlo simulations to calculate the Berezinskii-Kosterlitz-Thouless (BKT) temperature for the two-dimensional planar rotator model in the presence of no…
Low Temperature Static and Dynamic Behavior of the Two-Dimensional Easy-Axis Heisenberg Model
M. E. Gouvea, G. M. Wysin, S. A. Leonel +3
We apply the self-consistent harmonic approximation (SCHA) to study static and dynamic properties of the two-dimensional classical Heisenberg model with easy-axis anisotropy. The s…
