In the well-known path-integral approach, the scattering states for a quasi-1D ring with quasi-1D leads can be expressed in terms of spinless electrons subject to a fictitious magnetic flux. We show that spin-dependent quantum-interference effects in small rings are strongest for spatially inhomogeneous SO interactions, in which case spin currents can be controlled by a small external magnetic field. Mesoscopic spin Hall effects in four-terminal rings can also be understood in terms of the fictitious magnetic flux.", "revisions": [ { "version": "v2", "updated": "2007-10-26T23:00:31.000Z" } ], "analyses": { "keywords": [ "mesoscopic rings", "inhomogeneous spin-orbit coupling", "spin transport", "fictitious magnetic flux", "mesoscopic spin hall effects" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
