Query: Theory of Edge States in Systems with Rashba Spin-Orbit Coupling   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.
