The functional serves as a model of a translation-invariant Bose gas at positive temperature. We prove the existence of minimizers in the case of repulsive interactions given by a sufficiently regular two-body potential. Furthermore, we prove the existence of a phase transition in this model and provide its phase diagram.","lang":"eng"}],"oa":1,"date_created":"2019-02-14T13:40:53Z","publication_identifier":{"issn":["0003-9527"],"eissn":["1432-0673"]},"type":"journal_article","publication":"Archive for Rational Mechanics and Analysis","volume":229,"citation":{"ieee":"M.
