摘要: We present a 2D method for studying quantum transport through arbitrary geometries under the influence of both external magnetic fields and Rashba spin-orbit coupling. apply this to two geometries—a straight wire ring structure. Our results reveal precession spin-polarized modes in wire, conductance resonances due phase shifts from field effect. The arising effect are non-Abelian nature acquired by electrons propagating around ring.
