The thermodynamic properties of strong short-range attractive Yukawa fluids,k=10, 9, 8, and 7, are determined by combining the slab technique with thestandard and the replica exchange Monte Carlo (REMC) methods. A good agreementwas found among the coexistence curves of these systems calculated by REMC andthose previously reported in the literature. However, REMC allows exploring thecoexistence at lower temperatures, where dynamics turns glassy. To obtain thesurface tension we employed, for both methods, a procedure that yields thepressure tensor components for discontinuous potentials. The surface tensionresults obtained by the standard MC and REMC techniques are in good agreement.
