Zero-Point Motions in Trans-Polyacetylene

In order to substantiate the applicability of the Takayama-Lin-Liu-Maki model to conducting polymer, the Su-Schrieffer-Heeger model is generalized to include the effects of lattice zero-point motions on electronic properties. Beyond the treatment of the white-noise approximation, some significant electronic properties of Peierls-Fröhlich states are documented. The finding shows that the correlation of lattice motions suppresses the effects of zero-point motions on the electronic properties more seriously.
