Hanle Effect near Boundaries
Hans-Andreas Engel
The Hanle effect describes suppression of spin polarization due to precession in a magnetic field. This is a standard spintronics tool and it gives access to the spin lifetime of s…
Spin generation away from boundaries by nonlinear transport
Ilya G. Finkler, Hans-Andreas Engel, Emmanuel I. Rashba +1
In several situations of interest, spin polarization may be generated far from the boundaries of a sample by nonlinear effects of an electric current, even when such a generation i…
Quantum optical interface for gate-controlled spintronic devices
Hans-Andreas Engel, Jacob M. Taylor, Mikhail D. Lukin +1
We describe an opto-electronic structure in which charge and spin degrees of freedom in electrical gate-defined quantum dots can be coherently coupled to light. This is achieved vi…
Out-of-plane spin polarization from in-plane electric and magnetic fields
Hans-Andreas Engel, Emmanuel I. Rashba, Bertrand I. Halperin
We show that the joint effect of spin-orbit and magnetic fields leads to a spin polarization perpendicular to the plane of a two-dimensional electron system with Rashba spin-orbit…
Theory of Spin Hall Effects in Semiconductors
Hans-Andreas Engel, Emmanuel I. Rashba, Bertrand I. Halperin
Spin Hall effects are a collection of phenomena, resulting from spin-orbit coupling, in which an electrical current flowing through a sample can lead to spin transport in a perpend…
Small-angle impurity scattering and the spin Hall conductivity in 2D systems
A. V. Shytov, E. G. Mishchenko, H. -A. Engel +1
An arbitrarily small concentration of impurities can affect the spin Hall conductivity in a two-dimensional semiconductor system. We develop a Boltzmann-like equation that can be u…
