摘要

A ring with spin-orbit effects coupled to a conducting wire is shown to exhibit a phase delay which is spin dependent.The key is that the coupling of the ring to the wire is over an extended spatial range and not just along a single point;this breaks the symmetry and makes the ring states couple differently to forward and backward moving wire states.This results,for properly injected spin states,in a spin-flipping probability which is dependent on the energy of the injected electron and can therefore be easily controlled.Several systems are presented and shown to exhibit this effect including the basic ring which couples to a wire as well as a ring which mediates between two wires,and a spiral between two wires.
