This is a repulsive nonlinear Schrödinger functional whose quartic term is proportional to the scattering length of the interparticle interaction potential. We propose a new derivation of this limit problem, with a method that bypasses some of the technical difficulties that previous derivations had to face. The new method is based on a combination of Dyson\\'s lemma, the quantum de Finetti theorem and a second moment estimate for ground states of the effective Dyson Hamiltonian. It applies equally well to the case where magnetic fields or rotation are present."}],"month":"03","oa":1,"_id":"1143","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1503.07061"}],"language":[{"iso":"eng"}],"date_updated":"2025-09-22T14:10:16Z","page":"459 - 485","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","year":"2016","author":[{"id":"404092F4-F248-11E8-B48F-1D18A9856A87","full_name":"Nam, Phan","last_name":"Nam","first_name":"Phan"},{"first_name":"Nicolas","last_name":"Rougerie","full_name":"Rougerie, Nicolas"},{"orcid":"0000-0002-6781-0521","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","full_name":"Seiringer, Robert","last_name":"Seiringer","first_name":"Robert"}],"status":"public","volume":9,"isi":1,"article_processing_charge":"No","title":"Ground states of large bosonic systems: The gross Pitaevskii limit revisited","date_created":"2018-12-11T11:50:23Z","publisher":"Mathematical Sciences Publishers","external_id":{"isi":["000378287000006"],"arxiv":["1503.07061"]},"issue":"2","oa_version":"Preprint","arxiv":1,"ec_funded":1}]
