我们提出了当自旋进动长度与线宽度相当时，Rashba 自旋轨道耦合对量子线中能带结构、输运和相互作用效应的影响的分析和数值结果。仅占据最低自旋分裂子带的情况特别有趣，因为接近相同手性的费米点的电子可以具有近似平行的自旋。我们讨论了自旋相关输运的后果以及量子线中相互作用的有效 Tomonaga-Luttinger 描述。
We present analytical and numerical results for the effect of Rashba spin-orbit coupling on band structure, transport, and interaction effects in quantum wires when the spin precession length is comparable to the wire width. The situation with only the lowest spin-split subbands occupied is particularly interesting because electrons close to Fermi points of the same chirality can have approximately parallel spins. We discuss consequences for spin-dependent transport and effective Tomonaga-Luttinger descriptions of interactions in the quantum wire.
