Superfluid Transition and Specific Heat of the 2D <i>x</i>-<i>y</i> Model: Monte Carlo Simulation

We present results of large-scale Monte Carlo simulations of the 2D classical <i>x</i>-<i>y</i> model on the square lattice. We obtain high accuracy results for the superfluid fraction and for the specific heat as a function of temperature, for systems of size <inline-form...
