Spin dynamics in rolled-up two dimensional electron gases

Trushin, Maxim ; Schliemann, John



Abstract

A curved two-dimensional electron gas with spin�orbit interactions due to the radial confinement asymmetry is considered. At a certain relation between the spin�orbit coupling strength and curvature radius the tangential component of the electron spin becomes a conserved quantity for any spin-independent scattering potential that leads to a number of interesting effects such as persistent spin ...
