The dielectric response of a charge density wave (CDW) distorted electron—phonon system in the precritical region II. Macroscopic dielectric function and conductivity

Abstract

AbstractStarting with a selfconsistent approximation (I) for the calculation of the selfenergies of the electron and phonon system, the dielectric function is calculated in the small momentum limit for a quasi‐one‐dimensional system in the precritical region above the Peierls temperature.
