3d modeling of the peierls transition in TTF-TCNQ organic crystals

The Peierls structural transition in quasi-one-dimensional (Q1D) TTF-TCNQ organic crystals of is studied in the 3D approximation. Two the most important electronphonon interactions are considered. The analytic expression for the phonon polarization operator is obtained in the random phase approxim...
