Netteta quantitative formulation we now outline an approach which, by taking corre lation effects into account in the band model, leads to a localized description. This approach is precisely the Hubbard model which he originally introduced as a microscopic model to explain the Mott transition. The basic ingredient of the model is a collection of ...

NettetAn instanton method is proposed to investigate the quantum tunneling between two weakly-linked Bose-Einstein condensates confined in double-well potential traps. We point out some intrinsic pathologies in the earlier treatments of other authors and make an effort to go beyond these very simple zero order models. The tunneling amplitude may be …
