It is well‐known that to leading order the ground state energy is given by the (classical) Pekar energy. In this work, we establish the subleading correction, describing quantum fluctuation about the classical limit. Our proof applies to a model of a confined polaron, where both the electron and the polarization field are restricted to a set of finite volume, with linear size determined by the natural length scale of the Pekar problem."}],"publisher":"Wiley","volume":74,"date_updated":"2023-08-04T11:02:16Z","month":"03","page":"544-588","date_created":"2020-10-04T22:01:37Z","department":[{"_id":"RoSe"}],"title":"Quantum corrections to the Pekar asymptotics of a strongly coupled polaron","_id":"8603","ddc":["510"],"author":[{"last_name":"Frank","full_name":"Frank, Rupert","first_name":"Rupert"},{"last_name":"Seiringer","full_name":"Seiringer, Robert","first_name":"Robert","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6781-0521"}],"type":"journal_article","year":"2021","publication_status":"published","oa":1,"oa_version":"Published Version","acknowledgement":"Partial support through National Science Foundation GrantDMS-1363432 (R.L.F.) and the European Research Council (ERC) under the Euro-pean Union’s Horizon 2020 research and innovation programme (grant agreementNo 694227; R.S.), is acknowledged.
