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.", "revisions": [ { "version": "v5", "updated": "2007-01-13T18:15:31.000Z" } ], "analyses": { "keywords": [ "spin hall effect", "atoms creates effective magnetic fields", "opposite spin polarizations", "pure spin current", "neutral atomic system" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
