The characteristic length scales of the system at zero energy are set by the Coulomb length scale D and the Coulomb-modified effective range r eff. We study shallow bound states of charged particles with D >> r eff and show that these systems obey universal scaling laws different from neutral particles. An accurate description of these states requires both the Coulomb-modified scattering length and the effective range unless the Coulomb interaction is very weak (D -> ). Our findings are relevant for bound states whose spatial extent is significantly larger than the range of the attractive potential. These states enjoy universality – their character is independent of the shape of the short-range potential.","lang":"eng"}],"year":"2019","ddc":["530"],"publication_identifier":{"issn":["0370-2693"]},"oa_version":"Published Version","department":[{"_id":"MiLe"}],"article_type":"original","status":"public","date_published":"2019-11-10T00:00:00Z","publication_status":"published","day":"10","publication":"Physics Letters B","author":[{"last_name":"Schmickler","full_name":"Schmickler, C.H.","first_name":"C.H."},{"full_name":"Hammer, H.-W.","last_name":"Hammer","first_name":"H.-W."},{"first_name":"Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem","last_name":"Volosniev"}],"doi":"10.1016/j.physletb.2019.135016","_id":"6955","volume":798,"external_id":{"isi":["000494939000086"],"arxiv":["1904.00913"]},"intvolume":"       798","language":[{"iso":"eng"}],"quality_controlled":"1","oa":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png"},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file_date_updated":"2020-07-14T12:47:46Z","file":[{"file_id":"6974","checksum":"d27f983b34ea7dafdf356afbf9472fbf","date_created":"2019-10-25T12:47:04Z","file_name":"2019_PhysicsLettersB_Schmickler.pdf","relation":"main_file","access_level":"open_access","file_size":528362,"date_updated":"2020-07-14T12:47:46Z","content_type":"application/pdf","creator":"dernst"}]}
