Simple relationship between the virial-route hypernetted-chain and the compressibility-route Percus-Yevick values of the fourth virial coefficient.
As is well known, approximate integral equations for liquids, such as the hypernetted chain (HNC) and Percus-Yevick (PY) theories, are in general thermodynamically inconsistent in the sense that the macroscopic properties obtained from the spatial correlation functions depend on the route followed. In particular, the values of the fourth virial coefficient B(4) predicted by the HNC and PY appro...
متن کاملExact analytic expression for a subset of fourth virial coe cients of polydisperse hard sphere mixtures
It is surprisingly di cult to calculate analytic expressions for virial coe cients. Even the exact calculation of the second virial coe cient is in general extremely di cult. If particles have no other interaction than hard core repulsion, things are slightly easier. In the isotropic phase, the second virial coe cient B 2 of two arbitrary, convex particles A and B can be determined by [1]
متن کاملExact analytic expression for a subset of fourth virial coefficients of polydisperse hard sphere mixtures
We derive an exact, analytic expression for the fourth virial coefficient of a system of polydisperse spheres under the constraint that the smallest sphere has a radius smaller than a given function of the radii of the three remaining particles.
متن کاملThe fourth virial coefficient of anyons
We have computed by a Monte Carlo method the fourth virial coefficient of free anyons, as a function of the statistics angle θ. It can be fitted by a four term Fourier series, in which two coefficients are fixed by the known perturbative results at the boson and fermion points. We compute partition functions by means of path integrals, which we represent diagrammatically in such a way that the ...
متن کاملDensity functional for ternary non-additive hard sphere mixtures.
Based on fundamental measure theory, a Helmholtz free energy density functional for three-component mixtures of hard spheres with general, non-additive interaction distances is constructed. The functional constitutes a generalization of the previously given theory for binary non-additive mixtures. The diagrammatic structure of the spatial integrals in both functionals is of star-like (or tree-l...
