Query: Multi-fluid hydrodynamics in charge density waves with collective,
  electronic, and solitonic densities and currents   We present a general scheme to approach the space - time evolution of
deformations, currents, and the electric field in charge density waves related
to appearance of intrinsic topological defects: dislocations, their loops or
pairs, and solitons. We derive general equations for the multi-fluid
hydrodynamics taking into account the collective mode, electric field, normal
electrons, and the intrinsic defects. These equations may allow to study the
transformation of injected carriers from normal electrons to new periods of the
charge density wave, the collective motion in constrained geometry, and the
plastic states and flows. As an application, we present analytical and
numerical solutions for distributions of fields around an isolated dislocation
line in the regime of nonlinear screening by the gas of phase solitons.
