The hypernetted chain (HNC) and Percusâ€“Yevick (PY) integral equations are solved numerically for parallel hard spherocylinders of length-to-width ratios L/Ïƒ ranging from 0.5 to 5.0. The PY virial pressure is in excellent agreement with Monte Carlo data. The HNC equation gives evidence...

The Monte Carlo method has been used to compute the coefficients of the spherical harmonic expansion of the function y=g exp(Î²u) for a hard diatomic fluid. The â€˜â€˜seriesâ€™â€™ function S(12) is also computed from MC data by means of an integral equation procedure. Thus,...

Using Monte Carlo simulation, scaling, variational and mean-field arguments we investigate forces between charged spherical aggregates conferred by oppositely charged polymeric chains. Two types of polymer mediated attraction are found in this system, both of a bridging type but differing...

We recently applied a Wertheim integral equation theory (IET) and a thermodynamic perturbation theory (TPT) to the Mercedesâ€“Benz (MB) model of pure water. These analytical theories offer the advantage of being computationally less intensive than the Monte Carlo simulations by orders of...
