Beyond the Fröhlich Hamiltonian: Path integral treatment of large polarons in anharmonic solids
Matthew Houtput, Jacques Tempere
The properties of an electron in a typical solid are modified by the interaction with the crystal ions, leading to the formation of a quasiparticle: the polaron. Such polarons are…
