Abstract

Commensurate 1 4 and 1 3-filled bands in which the electrons are coupled to both intersite phonons and intramolecular vibrations are investigated. Unlike in the 1 2-filled band, the bond order wave and the charge density wave coexist and interact cooperatively for all values of the two electron-phonon coupling constants. Despite the coexistence of the two kinds of density waves, solitons have charges that are rational fractions. The relevance of the cooperative interaction in non-half-filled bands to the metal-insulator transitions in segregated stack charge-transfer solids is discussed.
