Seeing Topological Order and Band Inversion in Optical Diatomic Chain
Jun Jiang, Zhiwei Guo, Weiwei Zhu +4
Recent realizations of exotic topological states in condensed matter and cold atoms have advanced the exploration for topological characteristics, such as invariant topological ord…
Significant enhancement of magneto-optical effect in one-dimensional photonic crystals with magnetized epsilon-near-zero defect
Zhiwei Guo, Feng Wu, Chunhua Xue +4
Nonreciprocal (NOR) transmission with magneto-optical materials plays a critical role in a broad range of applications, such as optical isolation, all-optical signal processing, an…
Observation of the topological edge state in X-ray band
Qiushi Huang, Zhiwei Guo, Jiangtao Feng +5
The possibility of obtaining robust edge state of light by mimicking the topological properties of solid state system, have brought a profound impact on optical sciences. With the…
Actively controlling the topological transition of dispersion based on electrically controllable metamaterials
Zhiwei Guo, Haitao Jiang, Yong Sun +2
Topological transition of the iso-frequency contour (IFC) from a closed ellipsoid to an open hyperboloid, will provide unique capabilities for controlling the propagation of light.…
Simultaneous Observation of Topological Edge State and Exceptional Point in an Open and Non-Hermitian System
Weiwei Zhu, Xinsheng Fang, Dongting Li +4
This paper reports on the experimental observation of topologically protected edge state and exceptional point in an open and Non-Hermitian system. While the theoretical underpinni…
Loss revives bistable state near the exceptional point in a non-Hermitian microwave photonic meta-molecule
Kejia Zhu, Yong Sun, Jie Ren +1
By exploring the extraordinary property of exceptional points (EPs) in non-Hermitian systems, we here demonstrate that losses can play constructive roles in controlling bistable st…
