Density of states determined from Monte Carlo simulations.
We describe a method for calculating the density of states by combining several canonical Monte Carlo runs. We discuss how critical properties reveal themselves in g (epsilon) and demonstrate this by applying the method to several different phase transitions. We also demonstrate how this can used to calculate the conformal charge, where the dominating numerical method has traditionally been the transfer matrix.
