我们描述了几何扭转对电子沿着薄扭曲量子环的相干运动的影响。量子环中固有的几何扭转会触发电子本征态的量子相移，从而产生沿着扭转量子环流动的扭转引起的持续电流。讨论了检测电流所需的物理条件。
We describe the effects of geometric torsion on the coherent motion of electrons along a thin twisted quantum ring. The geometric torsion inherent in the quantum ring triggers a quantum phase shift in the electrons' eigenstates, thereby resulting in a torsion-induced persistent current that flows along the twisted quantum ring. The physical conditions required for detecting the current flow are discussed.
