论文摘要
本研究中，将自旋偏振电子划分为两个平行的转移量子量子霍尔边缘通道的半摩尔人分别为两个平行的共同批量批准。通过观察Aharonov-bohm振荡，在Mach-Zehnder干涉仪中，该分区过程是连贯的，该分区的可见性高达60％，该干涉仪构成了两个这样的半效果。设备特性高度稳定，这使该设备有望在量子信息处理的应用中有望。理论上是对梁切开过程进行建模的，并且数值模拟成功地重现了实验观察。伴随于自旋旋转的电子的隔板通过旋转轨道相互作用从轨道到自旋的角动量转移来解释。
A half-mirror that divides a spin-polarized electron into two parallel copropagating spin-resolved quantum Hall edge channels one half each is presented in this study. The partition process was coherent, as confirmed by observing the Aharonov-Bohm oscillation at a high visibility of up to 60% in a Mach-Zehnder interferometer, which comprised two such half-mirrors. The device characteristics were highly stable, making the device promising in the application of quantum information processing. The beam-splitting process is theoretically modelled, and the numerical simulation successfully reproduces the experimental observation. The partition of the electron accompanied by the spin rotation is explained by the angular momentum transfer from the orbital to the spin via spin-orbit interactions.
