Numerical Determination of the Distribution of Energies for the XY-model
R. Salazar, R. Toral, A. R. Plastino
Abstract
We compute numerically the distribution of energies W(E,N) for the XY-model with short-range and long-range interactions. We find that in both cases the distribution can be fitted to the functional form: W(E,N) ~ exp(N f(E,N)), with f(E,N) an intensive function of the energy.
