Localization of chiral edge states by the non-Hermitian skin effect
Gui-Geng Liu, Subhaskar Mandal, Peiheng Zhou +11
Quantum Hall systems host chiral edge states extending along the one-dimensional boundary of any two-dimensional sample. In solid state materials, the edge states serve as perfectl…
Realization of a quadrupole topological insulator phase in a gyromagnetic photonic crystal
Peiheng Zhou, Gui-Geng Liu, Zihao Wang +8
The field of topological photonics was initiated with the realization of a Chern insulator phase in a gyromagnetic photonic crystal (PhC) with broken time-reversal symmetry (T), ho…
Demonstration of broadband topological slow light
Fujia Chen, Haoran Xue, Yuang Pan +12
Slow-light devices are able to significantly enhance light-matter interaction due to the reduced group velocity of light, but a very low group velocity is usually achieved in a nar…
Magnetically tunable zero-index metamaterials
Yucong Yang, Yueyang Liu, Jun Qin +6
Zero-index metamaterials (ZIMs) feature a uniform electromagnetic mode over a large area in arbitrary shapes, enabling many applications including high-transmission supercouplers w…
Observation of Weyl point pair annihilation in a gyromagnetic photonic crystal
Gui-Geng Liu, Zhen Gao, Peiheng Zhou +9
Weyl semimetals are gapless three-dimensional (3D) phases whose bandstructures contain Weyl point (WP) degeneracies. WPs carry topological charge and can only be eliminated by mutu…
Generation and Focusing of Orbital Angular Momentum Based on Polarized Reflectarray at Microwave Frequency
Fengxia Li, Haiyan Chen, Yang Zhou +4
A novel polarized reflectarray is designed, fabricated, and experimentally characterized to show its flexibility and efficiency to control wave generation and focusing of orbital a…
