Asymptotic series for low-energy excitations of the Fröhlich Polaron at strong coupling
arXiv:2306.16373 · doi:10.2140/pmp.2025.6.281
Abstract
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.
