One-Mode Bose - Einstein Condensation and Bogoliubov Theory
2005, v.11, Issue 2, 267-282
The first ansatz of the Bogoliubov theory is based on hypothesis of existence of the one-mode Bose - Einstein (BE) condensation and on its stability with respect to two-body particle interaction. We present here some rigorous results, which are relevant to this hypothesis.
