Strong-Coupling Bose-Einstein Condensation
Hagen Kleinert
TL;DR
This paper develops a theoretical framework for Bose-Einstein condensation that applies across all interaction strengths, from weak to strong coupling regimes.
Contribution
It extends the existing theory of Bose-Einstein condensation to include arbitrary strong couplings, surpassing previous weak-coupling limitations.
Findings
Unified description of Bose-Einstein condensation across coupling regimes
Mathematical model valid for strong interactions
Potential implications for experimental systems
Abstract
We extend the theory of Bose-Einstein condensation from Bogoliubov's weak-coupling regime to arbirarily strong couplings.
