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 $T_{B K T}$ for the two-dimensional planar rotator model in the presence of no…
