We review the proof of an asymptotic expansion of its low-energy spectrum, eigenstates, and dynamics, which provides corrections to Bogoliubov theory to all orders in 1/ N. This is based on joint works with Petrat, Pickl, Seiringer, and Soffer. In addition, we derive a full asymptotic expansion of the ground state one-body reduced density matrix."}],"oa":1,"publication_identifier":{"eissn":["1089-7658"],"issn":["0022-2488"]},"publisher":"AIP Publishing","intvolume":"        63","author":[{"id":"A2E3BCBE-5FCC-11E9-AA4B-76F3E5697425","first_name":"Lea","last_name":"Bossmann","full_name":"Bossmann, Lea","orcid":"0000-0002-6854-1343"}],"article_processing_charge":"Yes (via OA deal)","external_id":{"arxiv":["2203.00730"],"isi":["000809648100002"]},"department":[{"_id":"RoSe"}],"keyword":["Mathematical Physics","Statistical and Nonlinear Physics"],"title":"Low-energy spectrum and dynamics of the weakly interacting Bose gas","doi":"10.1063/5.0089983","article_type":"original","project":[{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"oa_version":"Published Version","scopus_import":"1","issue":"6","status":"public","acknowledgement":"The author thanks Nataˇsa Pavlovic, Sören Petrat, Peter Pickl, Robert Seiringer, and Avy Soffer for the collaboration on Refs. 1, 2 and 21.
