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…
Experimental observation of non-Abelian topological charges and bulk-edge correspondence
Qinghua Guo, Tianshu Jiang, Ruo-Yang Zhang +5
In the past decades, topological concepts have emerged to classify matter states beyond the Ginzburg-Landau symmetry breaking paradigm. The underlying global invariants are usually…
Deterministic scheme for two-dimensional type-II Dirac points and experimental realization in acoustics
Xiaoxiao Wu, Xin Li, Ruo-Yang Zhang +7
Low-energy electrons near Dirac/Weyl nodal points mimic massless relativistic fermions. However, as they are not constrained by Lorentz invariance, they can exhibit tipped-over typ…
Angular momentum-dependent topological transport and its experimental realization using a transmission line network
Tianshu Jiang, Meng Xiao, Wenjie Chen +4
Novel classical wave phenomenon analogs of the quantum spin Hall effect are mostly based on the construction of pseudo-spins. Here we show that the non-trivial topology of a system…
Experimental Observation of Acoustic Weyl Points and Topological Surface States
Hao Ge, Xu Ni, Yuan Tian +6
Weyl points emerge as topological monopoles of Berry flux in the three-dimensional (3D) momentum space and have been extensively studied in topological semimetals. As the underlyin…
Nano-corrugation induced forces between electrically neutral plasmonic objects
Kun Ding, Han Hu, T. C. Leung +1
Recent advances in nanotechnology have created tremendous excitement across different disciplines but in order to fully control and manipulate nano-scale objects, we must understan…
The Existence of Topological Edge States in Honeycomb Plasmonic Lattices
Li Wang, Ruo-Yang Zhang, Meng Xiao +3
In this paper, we investigate the band properties of 2D honeycomb plasmonic lattices consisting of metallic nanoparticles. By means of the coupled dipole method and quasi-static ap…
Synthetic gauge fields and Weyl point in Time-Reversal Invariant Acoustic Systems
Meng Xiao, Wen-Jie Chen, Wen-Yu He +2
Inspired by the discovery of quantum hall effect and topological insulator, topological properties of classical waves start to draw worldwide attention. Topological non-trivial ban…
