Magnetically Induced Topological Evolutions of Exceptional Points in Photonic Bands

Author(s): Xingqi Zhao, Jiajun Wang, Wenzhe Liu, Lei Shi, and Jian Zi Exceptional points (EPs) have been widely studied in various non-Hermitian systems, exhibiting and underlying many unique topological properties. In photonic systems, multiple degrees of freedom of light enable the EPs with rich properties and high dimensional topology. In this Letter, we propose th… [Phys. Rev.
