Response of a purely dissipative incommensurate chain to large driving pulses.

Systems which obey purely dissipative equations of motion can exhibit behavior normally associated with inductive (i.e.inertial) response. An experimentally well-studied example is the transient current oscillations that can occur when a voltage pulse is applied to a sliding charge density wave. Detailed numerical studies of the nonlinear response of a purely dissipative harmonic chain in a sinusoidal potential are presented in order to understand the effects on the transient current of strong pinning potentials and of a sudden large changes in the driving field. The results are compared to the experimental results for the charge density wave systems K(0.3)MoO(3), and TaS(3).
