论文摘要
几何阶段在物理学中无处不在。它们充当了物理系统转化的回忆。在光学中，最突出的例子是pancharatnam-berry相和自旋重新定位阶段。相位和极化结构的最新技术进步导致发现了光的其他几何阶段。所有这些的基本机制由纤维束理论提供。在这个座谈会中，我们回顾了纤维束理论如何不仅阐明了光的几何阶段的起源，而且还为探索高维状态空间的基础奠定了基础，这对拓扑光子学和量子通信产生了影响。
Geometric phases are ubiquitous in physics; they act as memories of the transformation of a physical system. In optics, the most prominent examples are the Pancharatnam-Berry phase and the spin-redirection phase. Recent technological advances in phase and polarization structuring have led to the discovery of additional geometric phases of light. The underlying mechanism for all of these is provided by fibre bundle theory. In this colloquium, we review how fibre bundle theory does not only shed light on the origin of geometric phases of light, but also lays the foundations for the exploration of high dimensional state spaces, with implications for topological photonics and quantum communications.
