The result verifies the prediction of the random-phase approximation. Our proof refines the method of collective bosonization in three dimensions. We approximately diagonalize an effective Hamiltonian describing approximately bosonic collective excitations around the Hartree–Fock state, while showing that gapless and non-collective excitations have only a negligible effect on the ground state energy."}],"quality_controlled":"1","page":"885-979","external_id":{"arxiv":["2005.08933"],"isi":["000646573600001"]},"language":[{"iso":"eng"}],"scopus_import":"1","ddc":["510"],"date_created":"2020-05-28T16:48:20Z","status":"public","day":"03","_id":"7901","publication":"Inventiones Mathematicae","publication_status":"published","date_published":"2021-05-03T00:00:00Z","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","month":"05","publication_identifier":{"issn":["0020-9910"],"eissn":["1432-1297"]},"oa_version":"Published Version","publisher":"Springer","author":[{"last_name":"Benedikter","first_name":"Niels P","full_name":"Benedikter, Niels P","id":"3DE6C32A-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1071-6091"},{"last_name":"Nam","first_name":"Phan Thành","full_name":"Nam, Phan Thành"},{"first_name":"Marcello","full_name":"Porta, Marcello","last_name":"Porta"},{"last_name":"Schlein","first_name":"Benjamin","full_name":"Schlein, Benjamin"},{"id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","full_name":"Seiringer, Robert","orcid":"0000-0002-6781-0521","first_name":"Robert","last_name":"Seiringer"}],"file":[{"file_name":"2021_InventMath_Benedikter.pdf","relation":"main_file","date_updated":"2022-05-16T12:23:40Z","file_size":1089319,"file_id":"11386","content_type":"application/pdf","date_created":"2022-05-16T12:23:40Z","success":1,"creator":"dernst","checksum":"f38c79dfd828cdc7f49a34b37b83d376","access_level":"open_access"}]}
