Goldstone Bosons in Josephson Junctions
B. Dierckx, A. Verbeure
For a microscopic model of a Josephson junction the normal coordinates of the two junction Goldstone bosons are constructed and their dynamical spectrum is computed. The explicit d…
Imperfect Bose Gas with Attractive Boundary Conditions
Lieselot Vandevenne, Andre Verbeure
The free Bose gas with attractive boundary conditions is an interesting toy model for the study of Bose-Einstein Condensation (BEC), because one has BEC already in one dimension. H…
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…
Models with Recoil for Bose-Einstein Condensation and Superradiance
Joseph V. Pulé, André F. Verbeure, Valentin A. Zagrebnov
In this paper we consider two models which exhibit equilibrium BEC superradiance. They are related to two different types of superradiant scattering observed in recent experiments.…
Models for Equilibrium BEC Superradiance
Joseph V. Pule, Andre Verbeure, Valentin A. Zagrebnov
Motivated by recent experiments with superradiant Bose-Einstein Condensate (BEC) we consider simple microscopic models describing rigorously the interference of the two cooperative…
A microscopic model for Josephson currents
J. Lauwers, A. Verbeure
A microscopic model of a Josephson junction between two superconducting plates is proposed and analysed. For this model, the nonequilibrium steady state of the total system is expl…
