On 10 March 2020, the top physical journal Physical Review Letters published the research work lead by Rui Wang, et.al [Phys. Rev. Lett. 124, 105303 (2020)]. Their work proposed a novel quantum states in topological phonon systems, termed as “Symmetry-Protected Topological Triangular Weyl Complex”. Distinct from conventional Weyl systems with Weyl points appearing in pairs, a symmetry-protected topological triangular Weyl complex composed of three Weyl points is first identified in condensed matter physics. The triangular Weyl complex hosts unique surface arcs terminated at the projections of one double and two single Weyl points.
