Exciton-phonon coupling in the Frenkel and Wannier limits

Research output: Contribution to journal › Article › peer-review

Abstract

It is argued that a recent derivation of new Frenkel exciton-phonon coupling terms uses methods physically inappropriate for Frenkel excitons. A simple model for the unified treatment of Frenkel and Wannier exciton states is extended to give a unified treatment of the exciton-phonon coupling. Results of the conventional form emerge in both limits, with no new terms.
