CRITICAL TEMPERATURE OF TRAPPED INTERACTING BOSE GASES

摘要

A new model is proposed to study the effect of mutual interaction revealed in a re-cent experiment.1 Unlike conventional Hartree{Fock theory, which only studies onset interactions between indistinguishable interacting bosons, our model further includes the mutual interaction between the condensate component and the thermal component. The derived condensate fraction and transition temperature explain the experimental data in a reliable manner.
