Study of the perturbation to a Bose-Einstein gas
Abstract
We developed a new approach to the perturbation theory for the efffective Hamiltonian of condensate particles in Fock space. Using this new theory, we can easily analyze the effect of including a somewhat problematic term in the work of Ezawa et al. We thus showed that indeed the inclusion of this term in the perturbation potential is justified.
