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."}],"license":"https://creativecommons.org/licenses/by/4.0/","type":"journal_article","file":[{"date_updated":"2020-07-14T12:47:46Z","file_id":"6974","file_size":528362,"date_created":"2019-10-25T12:47:04Z","checksum":"d27f983b34ea7dafdf356afbf9472fbf","relation":"main_file","content_type":"application/pdf","creator":"dernst","access_level":"open_access","file_name":"2019_PhysicsLettersB_Schmickler.pdf"}],"day":"10","article_processing_charge":"No","month":"11","date_updated":"2023-08-30T07:06:42Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"file_date_updated":"2020-07-14T12:47:46Z","isi":1,"ddc":["530"],"intvolume":" 798","volume":798,"year":"2019","article_type":"original","citation":{"mla":"Schmickler, C.
