论文摘要
非热拓扑系统是对拓扑问题不断增长的领域的最新补充。在这项工作中，我们报告了多方半金属中的光驱动的特殊物理。驾驶不仅是控制特殊轮廓（EC）位置的关键要素，还具有生成新EC的能力。有趣的是，我们还展示了拓扑电荷分布和Lifshitz过渡，这些过渡可通过此类EC中的驱动场来控制。我们的发现提出了一个有前途的平台，用于对非热拓扑问题中特殊物理的操纵和控制。
Non-Hermitian topological systems are the newest additions to the growing field of topological matter. In this work, we report of the light-driven exceptional physics in a multi-Weyl semi-metal. The driving is not only a key ingredient to control the position of the exceptional contours (ECs), light also has the ability to generate new ECs. Interestingly, we also demonstrate topological charge distribution and Lifshitz transition, which are controllable by the driving field in such generated ECs. Our findings present a promising platform for the manipulation and control over exceptional physics in non-Hermitian topological matter.
