Popis: The renormalization of the mass of an electron interacting with many ions of a lattice via the long-range (Frohlich) electron-phonon interaction and optical absorption of electrons are studied at zero temperature. Ions are assumed to be isotropic three-dimensional oscillators. The optical conductivity and the renormalized mass of small adiabatic Frohlich polarons are calculated and compared with those of small adiabatic Holstein polarons.
