The Approximating Hamiltonian Method for the Imperfect Boson Gas

Abstract

The pressure for the Imperfect (Mean Field) Boson gas can be derived in several ways. The aim of the present note is to provide a new method based on the Approximating Hamiltonian argument which is extremely simple and very general.
