Decoupling of charge and spin density waves for a one-dimensional electron-phonon Peierls system with a half-filled band

Abstract

Decoupling of charge and spin density waves for a Peierls electron-phonon system with a half-filled band (polyacetylene) was achieved as a consequence of the vanishing of certain interaction terms in the fermion representation of electron field operators including spins due to the Pauli principle.
