Rashba模型的自旋-电荷漂移-扩散耦合方程

Coupled spin-charge drift-diffusion equations for the Rashba model

V. V. Bryksin, P. Kleinert

摘要:

本文导出了具有弱Rashba自旋轨道相互作用的偏置二维电子气的自旋电荷漂移扩散方程。基本方程形式上同意最近的结果自旋轨道耦合小极化子。结果表明,面内电场对均匀自旋系统的作用完全可以用面内磁场来描述。利用这一类比,我们预测的电场等效的汉勒效应等。

英文摘要:

Coupled spin-charge drift-diffusion equations are derived for a biased two-dimensional electron gas with weak Rashba spin-orbit interaction. The basic equations formally agree with recent results obtained for spin-orbit coupled small polarons. It is shown that effects of an in-plane electric field on a homogeneous spin system can completely be described by an associated in-plane magnetic field. Exploiting this analogy, we predict among other things the electric-field equivalent of the Hanle effect.
