Three-particle hyper-netted chain approximation

Abstract

The principles on which the two-particle convolution hyper-netted chain approximation of classical statistical mechanics is based, namely summation over a specific class of Yvon-Mayer diagrams and use of a variational principle, are used to derive a three-particle approximation. This approximation gives a symmetric three-particle correlation function and is applicable to a system with three-, as well as two-particle interactions. Show more
