Symmetry-Protected Ideal Type-II Weyl Phonons in CdTe
B. W. Xia, R. Wang, Z. J. Chen +2
Nontrivial low-energy excitations of crystalline solids have insightfully strengthened understanding of elementary particles in quantum field theory. Usually, topological quasipart…

Symmetry-Protected Topological Triangular Weyl Complex
R. Wang, B. W. Xia, Z. J. Chen +3
Weyl points are often believed to appear in pairs with opposite chirality. In this work, we show by first-principles calculations and symmetry analysis that single Weyl phonons wit…
