Four-Dimensional Higher-Order Chern Insulator and Its Acoustic Realization
Ze-Guo Chen, Weiwei Zhu, Yang Tan +2
We present a theoretical study and experimental realization of a system that is simultaneously a four-dimensional (4D) Chern insulator and a higher-order topological insulator (HOT…

Three-dimensional acoustic double-zero-index medium with a Dirac-like point
Changqing Xu, Guancong Ma, Ze-Guo Chen +4
We report a design and experimental realization of a three-dimensional (3D) acoustic double-zero-index medium (DZIM), whose effective mass density and compressibility are nearly ze…
