Popis: | We present Monte Carlo simulations of a generalization of the Feynman-Kikuchi model, which includes the possibility of vacancies and interactions between the particles undergoing exchange. By measuring the winding number (superfluid density) and density structure factor, we determine the phase diagram and show that it exhibits regions which possess both superfluid and charge ordering. |
