Topological classification for intersection singularities of exceptional surfaces in pseudo-Hermitian systems
Hongwei Jia, Ruo-Yang Zhang, Jing Hu +3
Exceptional points play a pivotal role in the topology of non-Hermitian systems, and significant advances have been made in classifying exceptional points and exploring the associa…
Optically reconfigurable quantum spin-valley Hall effect of light in coupled nonlinear ring resonator lattice
Haofan Yang, Jing Xu, Zhongfei Xiong +4
Scattering immune propagation of light in topological photonic systems may revolutionarize the design of integrated photonic circuits for information processing and communications.…
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…
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…
Optical pulling using topologically protected one-way-transport surface-arc waves
Neng Wang, Ruo-Yang Zhang, Qinghua Guo +2
This paper proposes a new method to achieve robust optical pulling of particles by using an air waveguide sandwiched between two chiral hyperbolic metamaterials. The pulling force…
