Restoration of non-Hermitian bulk-boundary correspondence by counterbalancing skin effect
Yi-Xin Xiao, Zhao-Qing Zhang, C. T. Chan
The non-Hermitian skin effect (NHSE) undermines the conventional bulk-boundary correspondence (BBC) since it results in a distinct bulk spectrum in open-boundary systems compared t…
Photonic topological Anderson insulators
Xiaohan Cui, Ruo-Yang Zhang, Zhao-Qing Zhang +1
That disorder can induce nontrivial topology is a surprising discovery in topological physics. As a typical example, Chern topological Anderson insulators (TAIs) have been realized…
Four-band non-Abelian topological insulator and its experimental realization
Tianshu Jiang, Qinghua Guo, Ruo-Yang Zhang +3
Very recently, increasing attention has been focused on non-Abelian topological charges, e.g. the quaternion group Q8. Different from Abelian topological band insulators, these sys…
Acoustic metamaterials with spinning components
Degang Zhao, Yao-Ting Wang, Kin-Hung Fung +2
Using both multiple scattering theory and effective medium theory, we find that an acoustic metamaterial consisting of an array of spinning cylinders can possess a host of unusual…
Anisotropic exceptional points of arbitrary order
Yi-Xin Xiao, Zhao-Qing Zhang, Zhi Hong Hang +1
A pair of anisotropic exceptional points (EPs) of arbitrary order are found in a class of non-Hermitian random systems with asymmetric hoppings. Both eigenvalues and eigenvectors e…
Experimental demonstration of an anisotropic exceptional point
Kun Ding, Guancong Ma, Z. Q. Zhang +1
Exceptional points (EPs) associated with a square-root singularity have been found in many non-Hermitian systems. In most of the studies, the EPs found are isotropic meaning that t…
