The molecula crystal model (Holstein model) is studied versus temperature and dimensionality by taking into account the effect of the intermolecular forces. The phonon dispersion relations strongly influence the polaron band narrowing factor.

Abstract
The molecula crystal model (Holstein model) is studied versus temperature and dimensionality by taking into account the effect of the intermolecular forces. The phonon dispersion relations strongly influence the polaron band narrowing factor.File in questo prodotto:
