论文摘要
我们提出了一种传导量子网络的理论，该理论说明了作用于自旋载体的阿贝利亚和非阿贝尔领域。我们应用这种方法来建模不同几何形状（例如平方和环）的介观旋转干涉仪的电导，从而再现了纳米结构的Inasga量子孔中的最新实验发现，该发现受到Rashba Spin-Orbit和Zeeman田地（例如Aharonov-casher-casher-casher-casher-casher Interference模式的操纵）。此外，通过引入额外的现场文本工程，我们设法挑出了先前未知的自旋抑制机制。我们注意到我们的方法也可以用于研究复杂网络和封闭系统的光谱特性。
We present a theory of conducting quantum networks that accounts for Abelian and non-Abelian fields acting on spin carriers. We apply this approach to model the conductance of mesoscopic spin interferometers of different geometry (such as squares and rings), reproducing recent experimental findings in nanostructured InAsGa quantum wells subject to Rashba spin-orbit and Zeeman fields (as, e.g., the manipulation of Aharonov-Casher interference patterns by geometric means). Moreover, by introducing an additional field-texture engineering, we manage to single out a previously unnoticed spin-phase suppression mechanism. We notice that our approach can also be used for the study of complex networks and the spectral properties of closed systems.
