Spin transport in semiconductor heterostructures with Rashba spin-orbit interaction in an electric field — •Olaf Bleibaum — Institut für Theoretische Physik, Otto-von-Guericke Universität, 39016 Magdeburg, PF 4120

Investigations on the impact of an electric field on spin transport processes are of much current interest. Particular attention is paid to systems with Rashba spin-orbit interaction. We have derived a system of diffusion equations, which also take into account the coupling between spin transport and charge transport, to get further insight into the impact of the electric field on the transport properties of such systems. In the talk we discuss the structure of these equations and investigate special solutions. Doing so, we pay particular attention to quantum and spin-charge coupling effects.
