Monte Carlo study of 2D generalized XY-models
- 181 Downloads
In this paper we study a recent generalization of the XY-model in two dimensions by using Monte Carlo method. The vortex density, specific heat, energy and critical temperature are obtained. Some results are compared with approximated analytical calculations. The nature of the phase transition as the generalization parameter varies is discussed.
