Anomalous Hall response of topological insulators
Dimitrie Culcer, S. Das Sarma
The anomalous Hall effect due to the surface conduction band of 3D topological insulators with an out-of-plane magnetization is \textit{always} dominated by an intrinsic topologica…
Semiclassical spin transport in spin-orbit-coupled systems
Dimitrie Culcer
This article discusses spin transport in systems with spin-orbit interactions and how it can be understood in a semiclassical picture. I will first present a semiclassical wave-pac…
Spin Orientation of Holes in Quantum Wells
R. Winkler, Dimitrie Culcer, S. J. Papadakis +2
This paper reviews the spin orientation of spin-3/2 holes in quantum wells. We discuss the Zeeman and Rashba spin splitting in hole systems that are qualitatively different from th…
Weak momentum scattering and the conductivity of graphene
Dimitrie Culcer, R. Winkler
Electrical transport in graphene offers a fascinating parallel to spin transport in semiconductors including the spin-Hall effect. In the weak momentum scattering regime the steady…
On the nature of steady states of spin distributions in the presence of spin-orbit interactions
Dimitrie Culcer, Roland Winkler
In the presence of spin-orbit interactions, the steady state established for spin distributions in an electric field is qualitatively different from the steady state for charge dis…
Generation of spin currents and spin densities in systems with reduced symmetry
Dimitrie Culcer, R. Winkler
We show that the spin-current response of a semiconductor crystal to an external electric field is considerably more complex than previously assumed. While in systems of high symme…
