Abstract

So far in this book we have dealt almost entirely with assemblies made up of weakly interacting particles, either localized or gaseous. This has really not been a matter of choice, but almost of necessity. The basic approach has been founded on the idea that the energy of the assembly is simply the sum of the individual one-particle energies, i.e. U = ∑ n j ε j . Without this simplification the mathematics gets out of hand (although some progress can be made if we start with the canonical or grand canonical approach).
