Query: Influences of Topological Defect on Spin Hall Effect   We study the influence of topological defect on the spin current as well as
the spin Hall effect. We find that the nontrivial deformation of the space-time
due to topological defect can generate a spin dependent current which then
induces an imbalanced accumulation of spin states on the edges of sample. The
corresponding spin-Hall conductivity has also been calculated for the
topological defect of a cosmic string. Comparing to the ordinary value, a
correction which is linear with mass density of the cosmic string appears. Our
approach to the dynamics of non-relativistic spinor in the presence of a
topological defect is based on the Foldy-Wouthuysen transformation. The spin
current is obtained in by using the extended Drude model which is independent
of the scattering mechanism.
