Renormalized energy of ground and first excited state of Fröhlich polaron in the range of weak coupling
The partial summing of infinite range of diagrams for the two-phonon mass operator of polaron described by Frohlich Hamiltonian is performed using the Feynman-Pines diagram technique. The renormalized spectral parameters of ground and first excited (phonon repeat) polaron state are accurately calcul...
