Unveiling Real Triple Degeneracies in Crystals: Exploring Link and Compound Structures
Wenwen Liu, Hanyu Wang, Biao Yang +1
With their non-Abelian topological charges, real multi-bandgap systems challenge the conventional topological phase classifications. As the minimal sector of multi-bandgap systems,…
Non-Abelian physics in light and sound
Yi Yang, Biao Yang, Guancong Ma +3
There has been a recent surge of interest in using light and sound as platforms for studying non-Abelian physics. Through a kaleidoscope of physical effects, light and sound provid…
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…
Edge and corner states in 2D non-Abelian topological insulators from an eigenvector frame rotation perspective
Tianshu Jiang, Ruo-Yang Zhang, Qinghua Guo +2
We propose the concept of 2D non-Abelian topological insulator which can explain the energy distributions of the edge states and corner states in systems with parity-time symmetry.…
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…
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,…
