Abstract
A new approach to the Peierls distortion is described, where the lattice distortion is induced by some means external to the system. This nonequilibrium technique removes the temperature limitations on the Peierls distortion and the limitation of phonon localization, and so can generate charge-density waves at an arbitrary temperature. A method is considered for coherent phonon generation and subsequent use with a quantum wire array to induce a charge-density-wave transition.
