Title: Mobile small polaron
Authors: Alexandrov, A.S.
Kornilovitch, P.E.
Issue Date: 1998
Abstract: Extending the Froehlich polaron problem to a discrete ionic lattice we study a polaronic state with a small radius of the wave function but a large size of the lattice distortion. We calculate the energy dispersion and the effective mass of the polaron with the 1/\lambda perturbation theory and with the exact Monte Carlo method in the nonadiabatic and adiabatic regimes, respectively. The "small" Froehlich polaron is found to be lighter than the small Holstein polaron by one or more orders of magnitude.
