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…
Experimental observation of non-Abelian earring nodal links in phononic crystals
Mudi Wang, Shan Liu, Qiyun Ma +7
Nodal lines are symmetry-protected one-dimensional band degeneracies in momentum space, which can appear in numerous topological configurations such as nodal rings, chains, links,…
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…
Topological one-way large-area waveguide states in magnetic photonic crystals
Mudi Wang, Ruo-Yang Zhang, Lei Zhang +4
We have theoretically and experimentally achieved large-area one-way transport by using heterostructures consisting of a domain of an ordinary photonic crystal (PC) sandwiched betw…
Chiral transport of pseudo-spinors induced by synthetic gravitational field in photonic Weyl metamaterials
Hongwei Jia, Ruo-Yang Zhang, Wenlong Gao +2
Weyl particles exhibit chiral transport property under external curved space-time geometry. This effect is called chiral gravitational effect, which plays an important role in quan…
Robust acoustic pulling using chiral surface waves
Neng Wang, Ruo-Yang Zhang, C. T. Chan
We show that long-range and robust acoustic pulling can be achieved by using a pair of one-way chiral surface waves supported on the interface between two phononic crystals compose…
