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…

Accidental degeneracy of double Dirac cones in a phononic crystal
Ze-Guo Chen, Xu Ni, Ying Wu +5
Artificial honeycomb lattices with Dirac cone dispersion provide a macroscopic platform to study the massless Dirac quasiparticles and their novel geometric phases. In this paper,…
