论文摘要
干涉法是一种强大的技术,用于提取有关系统波函数的有价值信息。在这项工作中,我们研究了旋转载体对弯曲的一维干涉电路中有效的田间纹理的反应,但要受到Rashba和Dresselhaus旋转轨相互作用的联合作用。通过使用量子网络技术,我们确定这两个非亚伯磁场与电路几何形状之间的相互作用修改了纺纱器的几何特性,尤其是在方形电路上,导致电子波函数的定位和量子电导的抑制。我们通过根据绕组数对相应的自旋纹理进行分类来提出拓扑解释。
Interferometry is a powerful technique used to extract valuable information about the wave function of a system. In this work, we study the response of spin carriers to the effective field textures developed in curved one-dimensional interferometric circuits subject to the joint action of Rashba and Dresselhaus spin-orbit interactions. By using a quantum network technique, we establish that the interplay between these two non-Abelian fields and the circuit's geometry modify the geometrical characteristics of the spinors, particularly on square circuits, leading to the localisation of the electronic wave function and the suppression of the quantum conductance. We propose a topological interpretation by classifying the corresponding spin textures in terms of winding numbers.
