Spin-orbit interactions of transverse sound
Shubo Wang, Guanqing Zhang, Xulong Wang +3
Spin-orbit interactions (SOIs) endow light with intriguing properties and applications such as photonic spin-Hall effects and spin-dependent vortex generations. However, it is coun…
Multi-dimensional wave steering with higher-order topological phononic crystal
Changqing Xu, Zeguo Chen, Guanqing Zhang +2
The recent discovery and realizations of higher-order topological insulators enrich the fundamental studies on topological phases. Here, we report three-dimensional (3D) wave-steer…
Relaying Topological Interface States for Negative Refraction of Bulk Waves
Hongchen Chu, Ze-Guo Chen, Yun Lai +1
Topological notions in physics have become a powerful perspective that leads to the discoveries of topological interface states (TISs). In this work, we present a scheme to achieve…
Direct Measurement of Topological Properties of an Exceptional Parabola
Weiyuan Tang, Kun Ding, Guancong Ma
Non-Hermitian systems can produce branch singularities known as exceptional points (EPs). Different from singularities in Hermitian systems, the topological properties of an EP can…
Landau-Zener Transition in Topological Acoustic Pumping
Ze-Guo Chen, Weiyuan Tang, Ruo-Yang Zhang +1
Quantized charge pumping is a robust adiabatic phenomenon uniquely existing in topologically nontrivial systems. Such topological pumping not only brings fundamental insights to th…
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…
