Query: Spin cloud induced around an elastic scatterer by the intrinsic
  spin-Hall effect   Similar to the Landauer electric dipole created around an impurity by the
electric current, a spin polarized cloud of electrons can be induced by the
intrinsic spin-Hall effect near a spin independent elastic scatterer. It is
shown that in the ballistic range around the impurity, such a cloud appears in
the case of Rashba spin-orbit interaction, even though the bulk spin-Hall
current is absent.
