Transition Temperature of Dilute, Weakly Repulsive Bose Gas
Masudul Haque, Andrei E. Ruckenstein
Within a quasiparticle framework, we reconsider the issue of computing the Bose-Einstein condensation temperature () in a weakly non-ideal Bose gas. The main result of this an…

Bose Condensation Without Broken Symmetries
Andrei E. Ruckenstein
This paper considers the issue of Bose-Einstein condensation in a weakly interacting Bose gas with a fixed total number of particles. We use an old current algebra formulation of n…
