具有自旋轨道耦合的二维电子自旋和密度动力学的对偶性

Duality of the spin and density dynamics for two-dimensional electrons with a spin-orbit coupling

I. V. Tokatly, E. Ya. Sherman

摘要:

我们研究了具有纯规范非阿贝尔自旋轨道场的二维电子气中的自旋动力学,其中具有平衡Rashba和Dresselhaus自旋轨道耦合的系统以及(110)轴生长的GaAs量子阱是典型的例子。我们证明了在没有自旋轨道耦合的系统中自旋演化和电子密度动力学的对偶性,这大大简化和深化了对自旋相关过程的分析。这种二元性为理解这类系统开辟了一个场所,这类系统对于它们在自旋电子学中的应用非常有趣,通过已知的没有自旋轨道耦合的系统特性。

英文摘要:

We study spin dynamics in a two-dimensional electron gas with a pure gauge non-Abelian spin-orbit field, for which systems with balanced Rashba and Dresselhaus spin-orbit couplings, and the (110)-axis grown GaAs quantum wells are typical examples. We demonstrate the duality of the spin evolution and the electron-density dynamics in a system without spin-orbit coupling, which considerably simplifies and deepens the analysis of spin-dependent processes. This duality opens a venue for the understanding of this class of systems, highly interesting for their applications in spintronics, through known properties of the systems without spin-orbit coupling.
