We prove that at weak coupling the critical temperature for a sample confined to a quadrant in two dimensions is strictly larger than the one for a half-space, which in turn is strictly larger than the one for  R^2. Furthermore, we prove that the relative difference of the critical temperatures vanishes in the weak coupling limit."}],"project":[{"grant_number":"I06427","_id":"bda63fe5-d553-11ed-ba76-a16e3d2f256b","name":"Mathematical Challenges in BCS Theory of Superconductivity"}],"publication_status":"published","article_type":"original","oa":1,"article_number":"e71","title":"Enhanced superconductivity at a corner for the linear BCS equation","file":[{"checksum":"b0919b3a14f2cb39f8df0e3f41b8d6f1","content_type":"application/pdf","file_name":"2025_ForumMathSigma_Roos.pdf","date_created":"2025-05-05T09:41:42Z","file_id":"19651","creator":"dernst","date_updated":"2025-05-05T09:41:42Z","access_level":"open_access","file_size":631645,"relation":"main_file","success":1}],"article_processing_charge":"Yes","external_id":{"isi":["001465985500001"],"arxiv":["2308.07115"]},"has_accepted_license":"1","author":[{"first_name":"Barbara","id":"5DA90512-D80F-11E9-8994-2E2EE6697425","full_name":"Roos, Barbara","orcid":"0000-0002-9071-5880","last_name":"Roos"},{"first_name":"Robert","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","full_name":"Seiringer, Robert","last_name":"Seiringer","orcid":"0000-0002-6781-0521"}],"OA_place":"publisher","tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"volume":13,"date_published":"2025-04-14T00:00:00Z","department":[{"_id":"RoSe"}],"corr_author":"1","date_updated":"2025-09-30T12:20:22Z","publisher":"Cambridge University Press","citation":{"short":"B.
