AI 中文摘要
拓扑态的探索已成为跨多个物理系统的一个活跃前沿。其中，莫比乌斯带作为一种典型结构，近期激发了有趣的光学对应物。在本工作中，我们通过使用光学模拟——光学莫比乌斯蜗牛，将该概念扩展到高维领域。具体而言，以斯格明子光束作为输入场，紧聚焦在三维空间中产生连续的莫比乌斯带族，形成蜗牛状的偏振拓扑纹理。此外，我们展示了全场偏振层析成像，并通过调节入射斯格明子光束的斯格明数实现了对该光学蜗牛纹理的可切换控制。我们的发现建立了低维与高维莫比乌斯几何之间的直接桥梁，为探索复杂空间拓扑和定制光与物质相互作用开辟了新平台。
英文摘要
The exploration of topological states has emerged as a vibrant frontier across diverse physical systems. Among these, the Möbius strip stands out as a canonical structure that has recently inspired intriguing optical physics.In this work, we extend this concept into the high-dimensional realm by using an optical analogue-the optical Möbius snail. Specifically, employing a skyrmionic beam as the input field, tight focusing yields a continuous family of Möbius strips that exists in three-dimensional space, giving rise to a snail-like polarization topological texture. Furthermore, we demonstrate full-field polarization tomography and achieve switchable control of this optical snail texture by tuning the Skyrme number of the incident skyrmionic beam. Our findings establish a direct bridge between low- and high-dimensional Möbius geometries, opening a new platform for exploring complex spatial topology and tailored light-matter interactions.
