Long Cycles in a Perturbed Mean Field Model of a Boson Gas
Teunis C. Dorlas, Philippe A. Martin, Joseph V. Pulé
In this paper we give a precise mathematical formulation of the relation between Bose condensation and long cycles and prove its validity for the perturbed mean field model of a Bo…
A Dicke Type Model for Equilibrium BEC Superradiance
Joseph V. Pule, Andre F. Verbeure, Valentin A. Zagrebnov
We study the effect of electromagnetic radiation on the condensate of a Bose gas. In an earlier paper we considered the problem for two simple models showing the cooperative effect…
The Approximating Hamiltonian Method for the Imperfect Boson Gas
Joseph V. Pule, Valentin A. Zagrebnov
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…
