Abstract
The liquid/vapor criticality of Coulombic and other fluids characterized by long-range interactions is investigated using canonical and grand-canonical Monte Carlo computer simulations. It is shown that while mixed-field finite-size scaling methods appear consistent with the theoretically expected universality class (Ising or classical depending on the potential), the constant-volume heat capacity shows a very strong dependence on the particular ensemble employed. Furthermore, for Coulombic and related systems, the heat capacities do not show the expected Ising-like behavior for the largest systems that have been simulated. The ensemble dependence of the constant-volume heat capacity and its still puzzling behavior will be discussed in some detail.
