Asymptotic series for low-energy excitations of the Fröhlich polaron at strong coupling Brooks, Morris ; https://orcid.org/0000-0002-6249-0928 Mitrouskas, David Johannes We consider the confined Fröhlich polaron and establish an asymptotic series for the low-energy eigenvalues in negative powers of the coupling constant. The coefficients of the series are derived through a two-fold perturbation approach, involving expansions around the electron Pekar minimizer and the excitations of the quantum field.
