Theory of Edge States in Systems with Rashba Spin-Orbit Coupling
arXiv:cond-mat/0407138 · doi:10.1103/PhysRevB.70.235344
Abstract
We study the edge states in a two dimensional electron gas with a transverse magnetic field and Rashba spin-orbit coupling. In the bulk, the interplay between the external field perpendicular to the gas plane and the spin-orbit coupling leads to two branches of states that, within the same energy window, have different cyclotron radii. For the edge states, surface reflection generates hybrid states with the two cyclotron radii. We analyze the spectrum and spin structure of these states and present a semiclassical picture of them.
