Nonreciprocal subdiffraction imaging with staggered gyromagnetic photonic crystals
Rui Ding, Tianshu Zhang, Jiarui Yu +4
Subdiffraction imaging serves as a novel technique to enhance the optical imaging resolution, where a backscattering-free approach remains so far unavailable. Here, we theoreticall…
Fragility of Unidirectional Transport in Weakly Disordered Photonic Chern Insulators
Xiaoxuan Shi, Tiantao Qu, Xianbin Wu +3
Photonic Chern insulators enable unidirectional light transport protected by nontrivial band topology -- essential for robust photonic integrated circuits and error-free communicat…
Unconventional topological edge states in one-dimensional gapless systems stemming from nonisolated hypersurface singularities
Hongwei Jia, Jing Hu, Ruo-Yang Zhang +7
Topologically protected edge states have been extensively studied in systems characterized by the topological invariants in band gaps (also called line gaps). In this study, we unv…
Band alignment effect in the topological photonic alloy
Tiantao Qu, Mudi Wang, Jun Chen +1
Recently, a photonic alloy with non-trivial topological properties has been proposed, based on the random mixing of Yttrium Iron Garnet (YIG) and magnetized YIG rods. When the dopi…
Bulk-spatiotemporal vortex correspondence in gyromagnetic double-zero-index media
Ruo-Yang Zhang, Xiaohan Cui, Yuan-Song Zeng +8
Photonic double-zero-index media, distinguished by concurrently zero-valued permittivity and permeability, exhibit extraordinary properties not found in nature. Remarkably, the not…
Three-dimensional non-reciprocal transport in photonic topological heterostructure of arbitrary shape
Mudi Wang, Ruo-Yang Zhang, Chenyu Zhang +6
Electromagnetic wave propagation in three-dimensional space typically suffers omnidirectional scattering when encountering obstacles. In this study, we employed Chern vectors to co…
Topological photonic alloy
Tiantao Qu, Mudi Wang, Xiaoyu Cheng +6
We present the new concept of photonic alloy as a non-periodic topological material. By mixing non-magnetized and magnetized rods in a non-periodic 2D photonic crystal configuratio…
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…
Experimental demonstration of non-adjacent band topology connecting multiple nodal links
Dongyang Wang, Biao Yang, Mudi Wang +5
Nodal links are special configurations of band degeneracies in the momentum space, where nodal line branches encircle each other. In PT symmetric systems, nodal lines can be topolo…
Experimental realization of chiral Landau levels in two-dimensional Dirac cone systems with inhomogeneous effective mass
Hongwei Jia, Mudi Wang, Shaojie Ma +3
Chiral zeroth Landau levels are topologically protected bulk states that give rise to chiral anomaly. Previous discussions on such chiral Landau levels are based on three-dimension…
Observation of boundary induced chiral anomaly bulk states and their transport properties
Mudi Wang, Qiyun Ma, Shan Liu +5
The robust transport of edge modes is perhaps the most useful property of topological materials. The existence of edge modes is guaranteed by the bulk-edge correspondence, which st…
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,…
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…
Experimental observation of sound-mediated stable configurations for polystyrene particles
Mudi Wang, Chunyin Qiu, Shenwei Zhang +3
Here we present an experimental observation of the self-organization effect of the polystyrene particles formed by acoustically-induced interaction forces. Two types of stable conf…
Acoustically mediated long-range interaction among multiple spherical particles exposed to a plane standing wave
Shenwei Zhang, Chunyin Qiu, Mudi Wang +2
In this work, we study the acoustically mediated interaction forces among multiple well-separated spherical particles trapped in the same node or antinode plane of a standing wave.…
