Quasiclassical approach and spin-orbit coupling — •Cosimo Gorini1, Peter Schwab1, Michael Dzierzawa1, and Roberto Raimondi2 — 1Institut für Physik, Universität Augsburg, 86135 Augsburg, Germany — 2Dipartimento di Fisica "E. Amaldi", Università di Roma Tre, 00146 Roma, Italy
We discuss the quasiclassical Green function method for a two-dimensional electron - or hole - gas in the presence of spin-orbit coupling, with emphasis on the meaning of the ξ-integration procedure. As an application we study spin and charge dynamics in such a system, with both magnetic and non-magnetic impurities present. We demonstrate in particular that, within our approach, the spin-Hall conductivity can easily be obtained from the spin-density continuity equation.
