Hydrodynamic theory of plastic flows with conversion

Abstract
Experimental studies show that the sliding state is essentially inhomogeneous with different effects near contacts, in the bulk or at obstacles. We present a general scheme to approach the space - time evolution of deformations, electric fields and currents with particular emphasize t o the current conversion process in Charge Density Waves. We derive general equations for the multifluid hydrodynamics of plastic flows which allow, in principle, to study the transformation of injected carriers from normal electrons to new periods, collective motion in constrained geometry as well as the plastic contribution to non-linear current-voltage characteristics.
