Non-Extensive Bose-Einstein Condensation Model
T. Michoel, A. Verbeure
The imperfect Boson gas supplemented with a gentle repulsive interaction is completely solved. In particular it is proved that it has non-extensive Bose-Einstein condensation, i.e.…
Interferencing in coupled Bose-Einstein condensates
T. Michoel, A. Verbeure
We consider an exactly soluble model of two Bose-Einstein condensates with a Josephson-type of coupling. Its equilibrium states are explicitly found showing condensation and sponta…
Goldstone Boson Normal Coordinates
T. Michoel, A. Verbeure
The phenomenon of spontaneous symmetry breaking is well known. It is known to be accompanied with the appearance of the `Goldstone boson'. In this paper we construct the canonical…
Mathematical Structure of Magnons in Quantum Ferromagnets
T. Michoel, A. Verbeure
We provide the mathematical structure and a simple, transparent and rigorous derivation of the magnons as elementary quasi-particle excitations at low temperatures and in the infin…
Goldstone Boson Normal Coordinates in Interacting Bose Gases
T. Michoel, A. Verbeure
For the phenomenon of Bose-Einstein condensation we construct the canonical pair of field operators of the Goldstone Bosons explicitly as fluctuation operators in the ground state.…
