Abstract: 
We propose an optical means to realize a spin hall effect (SHE) in neutral atomic system by
coupling the internal spin states of atoms to radiation. The interaction between the external optical
fields and the atoms creates effective magnetic fields that act in opposite directions on “electrically”
neutral atoms with opposite spin polarizations. This effect leads to a Landau level structure for
each spin orientation in direct analogy with the familiar SHE in semiconductors. The conservation
and topological properties of the spin current, and the creation of a pure spin current are discussed.
