论文摘要

我们研究了支持自旋轨道相互作用的无序介观设备。连接到四个半无限铅的系统,嵌入了Landauer-Buttiker设置中的量子量,并根据我们的分析表现出旋转厅角波动。我们在数值上显示了通过电荷电流到旋转电流中介导的极化的通用波动的指纹。我们的研究表明,我们的分析和数值结果与最新实验的完全兼容性。此外,我们在Rashba 2deg中展示了旋转厅效应的通用特征。所有结果表明,在许多情况下,微观参数与电荷转换和电荷转换和电荷转换的相关性不可避免地导致通用数量。

We investigate a disorderly mesoscopic device that supports spin-orbit interaction. The systemis connected to four semi-infinite leads embedded in the Landauer-Buttiker setup for quantumtransport and, according to our analysis, exhibits spin Hall angle fluctuations. We show analyticallyand numerically the fingerprint of the universal fluctuation of the polarization mediated by theconversion of charge current into spin current. Our investigation shows the complete compatibilityof our analytical and numerical results with the most recent experiments. Furthermore, we shownonzero and universal features of spin Hall effect in Rashba 2DEG with disorder. All the resultsshow the relevance of microscopic parameters for electronic transport with charge-spin conversionand, in many cases, inevitably lead to universal numbers.
