Asymptotic series for low-energy excitations of the Fr\"ohlich Polaron at strong coupling

We consider the confined Fr\"ohlich 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 minimize...
