Three-dimensional Electromagnetic Void Space
Changqing Xu, Hongchen Chu, Jie Luo +3
We report a realization of three-dimensional (3D) electromagnetic void space. Despite occupying a finite volume of space, such a medium is optically equivalent to an infinitesimal…

Exceptional points make an astroid in non-Hermitian Lieb lattice: evolution and topological protection
Yi-Xin Xiao, Kun Ding, Ruo-Yang Zhang +2
An astroid-shaped loop of exceptional points (EPs), comprising four cusps, is found to spawn from the triple degeneracy point in the Brillouin zone (BZ) of a Lieb lattice with near…

Observation of Antichiral Edge States in a Circuit Lattice
Yuting Yang, Dejun Zhu, Zhi Hong Hang +1
We constructed an electrical circuit to realize a modified Haldane lattice exhibiting the unusual phenomenon of antichiral edge states. The circuit consists of a network of inducto…
