Demonstration of acoustic high-order Stiefel-Whitney semimetal in bilayer graphene sonic crystals
Xiao Xiang, Xiang Ni, Feng Gao +4
Recently, higher-order topological phases have endowed materials many exotic topological phases. For three-dimensional (3D) higher-order topologies, it hosts topologically protecte…

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…
