The bound is asymptotically sharp at large coupling. In combination with a corresponding upper\r\nbound proved earlier (Mitrouskas et al. in Forum Math. Sigma 11:1–52, 2023), it shows that the energy is approximately\r\nparabolic below the continuum threshold, and that the polaron’s effective mass (defined as the semi-latus rectum of the\r\nparabola) is given by the celebrated Landau–Pekar formula. In particular, it diverges as α4 for large coupling constant α.\r\n"}],"external_id":{"arxiv":["2211.03353"]},"language":[{"iso":"eng"}],"year":"2024","publisher":"Springer Nature","corr_author":"1","department":[{"_id":"RoSe"}],"article_processing_charge":"Yes (in subscription journal)","citation":{"chicago":"Brooks, Morris, and Robert Seiringer. “The Fröhlich Polaron at Strong Coupling: Part II — Energy-Momentum Relation and Effective Mass.” Publications Mathematiques de l’Institut Des Hautes Etudes Scientifiques.
