非均匀磁场中具有自旋轨道和塞曼相互作用的自旋蛇态

Spin snake states with spin-orbit and Zeeman interactions in an inhomogeneous magnetic field

Vahram Grigoryan

摘要:

研究了Bychkov-Rashba自旋轨道、Zeeman相互作用和非均匀磁场的联合作用下垂直于二维电子系统的自旋边缘态。我们解析计算了系统中的自旋边缘态(自旋蛇轨道)的频谱,其中磁场在横向方向上表现出不连续的跳跃,并改变其符号的磁性界面。在2DES中获得的磁自旋边缘状态表现出几个有趣的特性:特别是,电子反转其传播方向在有限的动量值。

英文摘要:

We study the spin edge states, induced by the combined effect of Bychkov-Rashba spin-orbit, Zeeman interactions and inhomogeneous magnetic field, exposed perpendicularly to two-dimensional electron systems. We calculate analytically the spectrum of the spin edge states (the spin snakes orbits) in systems where the magnetic field exhibits a discontinuous jump in the transverse direction and changes its sign at the magnetic interface. The obtained magnetic spin edge states in a 2DES exhibit several interesting properties: in particular, electrons reverse their propagation direction at finite values of their momentum.
