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