Spin-orbit interactions and spin-currents from an exact-exchange   Kohn-Sham method
  An exact-exchange spin-current Kohn-Sham method to treat non-collinear spin, magnetic effects, currents, spin-currents, and spin-orbit interactions self-consistently on equal footing is introduced. Spin-orbit interactions are shown to induce spin-currents. Results for silicon and germanium are presented.
