Cooperative and non-linear phenomena at the neutral-ionic phase transition

Condensed Matter 2007-05-23 v1

Abstract

The complex interplay among on-site energy, Hubbard U, and coupling to Holstein and Peierls phonons at the neutral-ionic phase transition is discussed using diagrammatic valence bond calculations. The charge transfer and dimerization amplitudes and the infrared intensity of molecular vibrations are studied in the transition region.
