We study the Pauli-Fierz Hamiltonian associated with this system at a fixed total momentum. For small enough values of the fine-structure constant, we prove that the ground state is unique. This result reflects the hyperfine structure of the hydrogen atom ground state.", "revisions": [ { "version": "v1", "updated": "2011-12-02T09:51:58.000Z" } ], "analyses": { "subjects": [ "81V10", "81V45", "81Q10", "81Q15" ], "keywords": [ "dressed hydrogen atom ground state", "non-relativistic", "hyperfine splitting", "uniqueness", "standard model" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/s00220-012-1625-6", "journal": "Communications in Mathematical Physics", "year": 2013, "month": "Apr", "volume": 319, "number": 2, "pages": 425 }, "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013CMaPh.319..425A" } } }
