Query: Nonlinear Ohmic Dissipation in Axisymmetric DC and RF Driven Rotating
  Plasmas   An axisymmetric fully ionized plasma rotates around its axis when a charge
separation between magnetic surfaces is produced from DC fields or RF waves. On
each magnetic surface both electrons and ions obey the isorotation law and
perform an azimuthal E cross B rotation at the same angular velocity. When
Coulomb collisions are taken into account such a flow displays no Ohmic current
short circuiting of the charge separation and thus no linear dissipation. A
nonlinear Ohmic response appears when inertial effects are considered,
providing a dissipative relaxation of the charge separation between the
magnetic surfaces. This nonlinear conductivity results from an interplay
between Coriolis, centrifugal and electron-ion collisional friction forces.
This phenomena is identified, described and analyzed. In addition, both the
quality factor of angular momentum storage as well as the efficiency of wave
driven angular momentum generation are calculated and shown to be independent
of the details of the charge separation processes.
