Abstract:

We show that a finite magnetic flux threading a multichannel semiconductor ring can induce spin polarization at the borders of the sample when the Rashba spin-orbit interaction is taken into account. The spin polarization has an opposite sign on the two borders giving rise to a spin accumulation effect in the absence of external electric fields or currents. In addition the persistent charge current (PC) is investigated. As a consequence of the multichannel nature of the ring, the signature of the spin-orbit interaction in the PC cannot be encoded in a single effective topological phase. © 2005 The American Physical Society.
