Anomalous Spin-Related Quantum Phase in Mesoscopic Hole Rings
arXiv:0905.2661 · doi:10.1103/PhysRevB.81.155326
Abstract
We have obtained numerically exact results for the spin-related geometric quantum phases that arise in p-type semiconductor ring structures. The interplay between gate-controllable (Rashba) spin splitting and quantum-confinement-induced mixing between hole-spin states causes a much higher sensitivity of magnetoconductance oscillations to external parameters than previously expected. Our results imply a much-enhanced functionality of hole-ring spin-interference devices and shed new light on recent experimental findings.
