Excitation of electric-field-driven spin remagnetization waves on a cylindrical surface with spin-orbit interaction

Elementary excitations of a two-dimensional electron gas confined to a cylindrical surface are theoretically studied on the basis of coupled spin-charge drift-diffusion equations. The electric-field-mediated eigenmodes can be optically excited by an oscillating interference pattern. For a cylinder with a given radius, weakly damped resonances due to spin remagnetization waves are identified in the steady-state charge current response.
