Electromechanical Properties of Charge-Density-Wave Conductors

Abstract

A model of two mutally incommensurate, interacting, dynamical, many-body systems is presented and solved. Quasiperiodic forms are shown to describe both the dc properties and the complete set of linear excitations. By use of one system to represent the crystal lattice and the other a charge-density wave (CDW), all the recently discovered, and as yet unexplained, electromechanical properties of CDW conductors are shown to occur in this model. The internal degrees of freedom of the CDW are shown to be of central importance.
