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…
Theory of Spin Hall conductivity in n-doped GaAs
Hans-Andreas Engel, Bertrand I. Halperin, Emmanuel I. Rashba
We develop a theory of extrinsic spin currents in semiconductors, resulting from spin-orbit coupling at charged scatterers, which leads to skew scattering and side jump contributio…
Controlling Spin Qubits in Quantum Dots
Hans-Andreas Engel, L. P. Kouwenhoven, Daniel Loss +1
We review progress on the spintronics proposal for quantum computing where the quantum bits (qubits) are implemented with electron spins. We calculate the exchange interaction of c…
Probing Single-Electron Spin Decoherence in Quantum Dots using Charged Excitons
Oliver Gywat, Hans-Andreas Engel, Daniel Loss
We propose to use optical detection of magnetic resonance (ODMR) to measure the decoherence time T_{2} of a single electron spin in a semiconductor quantum dot. The electron is in…
Asymmetric Quantum Shot Noise in Quantum Dots
Hans-Andreas Engel, Daniel Loss
We analyze the frequency-dependent noise of a current through a quantum dot which is coupled to Fermi leads and which is in the Coulomb blockade regime. We show that the asymmetric…
Measurement efficiency and n-shot read out of spin qubits
Hans-Andreas Engel, Vitaly Golovach, Daniel Loss +4
We consider electron spin qubits in quantum dots and define a measurement efficiency e to characterize reliable measurements via n-shot read outs. We propose various implementation…
