Abstract

It is a paradox that the measured frequency-dependent linear conductivity of sliding charge-density-wave (CDW) materials is well described by a purely dissipative model of CDW motion, but several experiments involving the nonlinear response have demonstrated inductive effects characteristic of inertial systems. We show here that these results can be reconciled within a strongly dissipative model of CDW dynamics, provided the internal elastic degrees of freedom are taken into account. As a consequence, we predict a ‘‘ringing’’ oscillation of the CDW when the dc driving field is suddenly changed above the threshold.
