Abstract:
In this paper we study a recent generalization of the XY-model in two
dimensions by using Monte Carlo method.
The vortex density, specic 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.
