New approach to the small polaron conductivity problem

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

A model of electrons coupled to the damped lattice-oscillators is made the basis for calculation of the small polaron conductivity in the infrared frequency range. The inclusion of damping prevents the occurrence of singularities. Under the assumption of a weak damping a closed formula for the real part of conductivity is deduced which unifies the low-temperature as well as the high-temperature approximations.
