Small adiabatic polaron with a long-range electron-phonon interaction

Abstract

Two-site single electron system interacting with many vibrating ions of a lattice via a long-range (Fröhlich) electron-phonon interaction is studied in the adiabatic regime. The renormalised hopping integral of small adiabatic Fröhlich polarons is calculated and compared with the hopping integral of small adiabatic Holstein polarons.
