论文摘要
我们提出并表明，光的应用导致了一个有趣的平台，用于控制非富裕拓扑系统中的特殊点。我们使用三种不同的非富特系统（Nodal Line Semimetals，Semi-Dirac Semimetals和Dirac Semimetals）演示了我们的建议，并表明使用Light Inleumination可以设计出特殊点的位置和稳定性。我们说明了这些模型的拓扑特性，并绘制了其光驱动的拓扑相变。
We propose and show that application of light leads to an intriguing platform for controlling exceptional points in non-Hermitian topological systems. We demonstrate our proposal using three different non-Hermitian systems -- nodal line semimetals, semi-Dirac semimetals and Dirac semimetals -- and show that using illumination with light one can engineer the positions and stability of exceptional points. We illustrate the topological properties of these models and map out their light-driven topological phase transitions.
