自旋轨道规范与量子自旋霍尔效应

Spin-Orbit gauge and quantum spin Hall effect

B. Basu, P. Bandyopadhyay

摘要:

我们证明了Rashba和Dresselhaus相互作用的非Abel自旋轨道规范场强度,当分裂为两个Abel场强度时,系统的哈密顿量可以重新表示为两个耦合参数之间具有特定关系的Landau能级问题.量子能级由具有相反手征的上下自旋产生,并导致量子自旋霍尔效应。

英文摘要:

We have shown that the non-Abelian spin-orbit gauge field strength of the Rashba and Dresselhaus interactions, when split into two Abelian field strengths, the Hamiltonian of the system can be re-expressed as a Landau level problem with a particular relation between the two coupling parameters. The quantum levels are created with up and down spins with opposite chirality and leads to the quantum spin Hall effect.
