Spin-Hall effect: Back to the Beginning on a Higher Level
Jairo Sinova, Shuichi Murakami, Shun-Qing Shen +1
The phenomena of the spin-Hall effect, initially proposed over three decades ago in the context of asymmetric Mott skew scattering, was revived recently by the proposal of a possib…
Transverse electric current induced by optically injected spin current in cross-shaped InGaAs/InAlAs system
Jian Li, Xi Dai, Shun-Qing Shen +1
We examine electric response of a linearly polarized light normally shed on a cross-shaped quasi 2-dimensional InGaAs/InAlAs system with structure inversion asymmetry. The photo-ex…
Spin and orbital valence bond solids in a one-dimensional spin-orbital system: Schwinger boson mean field theory
Peng Li, Shun-Qing Shen
A generalized one-dimensional spin-orbital model is studied by Schwinger boson mean-field theory (SBMFT). We explore mainly the dimer phases and clarify how to…
Spin transverse force on spin current in an electric field
Shun-Qing Shen
As a relativistic quantum mechanical effect, it is shown that the electric field exerting a transverse force on an electron spin 1/2 only if the electron is moving and the spin is…
Charge Hall effect driven by spin-dependent chemical potential gradients and Onsager relations in mesoscopic systems
E. M. Hankiewicz, Jian Li, Tomas Jungwirth +3
We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron an…
Edge Spin Current and Spin Polarization in Quantum Hall Regime
Yun-Juan Bao, Huai-Bing Zhuang, Shun-Qing Shen +1
We study the edge spin current and spin polarization in a two-dimensional electron gas with spin-orbit coupling in the presence of a perpendicular magnetic field. The edge effect r…
