For suitable interaction potentials that have a strong enough attractive tail in order to allow for two-body bound states, but are otherwise sufficiently repulsive to guarantee stability of the system, we show that in the low-density limit the ground state of this model consists of a Bose–Einstein condensate of fermion pairs. The latter can be described by means of the Gross–Pitaevskii energy functional."}],"intvolume":" 19","status":"public","ddc":["510","539"],"title":"Bogolubov–Hartree–Fock theory for strongly interacting fermions in the low density limit","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","_id":"1259","oa_version":"Published Version","file":[{"content_type":"application/pdf","file_size":506242,"creator":"system","access_level":"open_access","file_name":"IST-2016-702-v1+1_s11040-016-9209-x.pdf","checksum":"9954f685cc25c58d7f1712c67b47ad8d","date_created":"2018-12-12T10:09:13Z","date_updated":"2020-07-14T12:44:42Z","relation":"main_file","file_id":"4736"}],"pubrep_id":"702","scopus_import":1,"has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"01","citation":{"mla":"Bräunlich, Gerhard, et al. “Bogolubov–Hartree–Fock Theory for Strongly Interacting Fermions in the Low Density Limit.” Mathematical Physics, Analysis and Geometry, vol. 19, no. 2, 13, Springer, 2016, doi:10.1007/s11040-016-9209-x.","short":"G.
