垂直磁场作用下二维空穴气中自旋极化的振荡

Oscillation of spin polarization in a two-dimensional hole gas under a perpendicular magnetic field

P. Kleinert, V. V. Bryksin

摘要:

研究了强约束二维空穴气体在垂直磁场作用下的自旋电荷耦合。该研究是基于自旋电荷耦合漂移扩散方程从量子动力学方程以精确的方式。自旋-轨道相互作用导致额外的面外自旋极化。这种贡献表现出持续的振荡模式在强耦合制度。

英文摘要:

Spin-charge coupling is studied for a strongly confined two-dimensional hole gas subject to a perpendicular magnetic field. The study is based on spin-charge coupled drift-diffusion equations derived from quantum-kinetic equations in an exact manner. The spin-orbit interaction induces an extra out-of-plane spin polarization. This contribution exhibits a persistent oscillatory pattern in the strong-coupling regime.
