Magnetically Controllable Multimode Interference in Topological Photonic Crystals
Weiyuan Tang, Mudi Wang, Shaojie Ma +2
Topological photonic insulators show promise for applications in compact integrated photonic circuits due to their ability to transport light robustly through sharp bendings. The n…
Realization and Topological Properties of Third-Order Exceptional Lines Embedded in Exceptional Surfaces
Weiyuan Tang, Kun Ding, Guancong Ma
As the counterpart of Hermitian nodal structures, the geometry formed by exceptional points (EPs), such as exceptional lines (ELs), entails intriguing spectral topology. We report…
Experimental Realization of Non-Abelian Permutations in a Three-State Non-Hermitian System
Weiyuan Tang, Kun Ding, Guancong Ma
Eigenstates of a non-Hermitian system exist on complex Riemannian manifolds, with multiple sheets connecting at branch cuts and exceptional points (EPs). These eigenstates can evol…
Experimental Realization of Weyl Exceptional Rings in a Synthetic Three-Dimensional Non-Hermitian Phononic Crystal
Zheng-wei Li, Jing-jing Liu, Ze-Guo Chen +5
Weyl points (WPs) are isolated degeneracies carrying quantized topological charges, and are therefore robust against Hermitian perturbations. WPs are predicted to spread to the Wey…
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…
