--- res: bibo_abstract: - We provide a definition of the effective mass for the classical polaron described by the Landau–Pekar (LP) equations. It is based on a novel variational principle, minimizing the energy functional over states with given (initial) velocity. The resulting formula for the polaron's effective mass agrees with the prediction by LP (1948 J. Exp. Theor. Phys. 18 419–423).@eng bibo_authorlist: - foaf_Person: foaf_givenName: Dario foaf_name: Feliciangeli, Dario foaf_surname: Feliciangeli foaf_workInfoHomepage: http://www.librecat.org/personId=41A639AA-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0003-0754-8530 - foaf_Person: foaf_givenName: Simone Anna Elvira foaf_name: Rademacher, Simone Anna Elvira foaf_surname: Rademacher foaf_workInfoHomepage: http://www.librecat.org/personId=856966FE-A408-11E9-977E-802DE6697425 orcid: 0000-0001-5059-4466 - foaf_Person: foaf_givenName: Robert foaf_name: Seiringer, Robert foaf_surname: Seiringer foaf_workInfoHomepage: http://www.librecat.org/personId=4AFD0470-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-6781-0521 bibo_doi: 10.1088/1751-8121/ac3947 bibo_issue: '1' bibo_volume: 55 dct_date: 2022^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/1751-8113 - http://id.crossref.org/issn/1751-8121 dct_language: eng dct_publisher: IOP Publishing@ dct_title: The effective mass problem for the Landau-Pekar equations@ ...
