Rashba自旋轨道耦合量子线中的倏逝态

Evanescent states in quantum wires with Rashba spin-orbit coupling

Llorens Serra, David Sanchez, Rosa Lopez

摘要:

本文讨论了考虑Rashba自旋轨道相互作用的准一维量子线中倏逝态的计算。我们提出了一个计算算法,设计的情况下,纵向和横向运动耦合。文中给出了几种情况下的色散关系,说明了所提出的计算方法的可行性。作为一个实际应用,我们讨论了含有电位阶跃的导线的解。

英文摘要:

We discuss the calculation of evanescent states in quasi-one-dimensional quantum wires in the presence of Rashba spin-orbit interaction. We suggest a computational algorithm devised for cases in which longitudinal and transverse motions are coupled. The dispersion relations are given for some selected cases, illustrating the feasibility of the proposed computational method. As a practical application, we discuss the solutions for a wire containing a potential step.
