Giant Chern number of a Weyl nodal surface without upper limit
Junzhang Ma, S. -N. Zhang, J. P. Song +15
Weyl nodes can be classified into zero-dimensional (0D) Weyl points (WPs), 1D Weyl nodal lines (WNL) and 2D Weyl nodal surfaces (WNS), which possess finite Chern numbers. Up to dat…
Observation of a singular Weyl point surrounded by charged nodal walls in PtGa
J. -Z. Ma, Q. -S. Wu, M. Song +17
Constrained by the Nielsen-Ninomiya no-go theorem, in all so-far experimentally determined Weyl semimetals (WSMs) the Weyl points (WPs) always appear in pairs in the momentum space…
Manipulation of type-I and type-II Dirac points in PdTe2 superconductor by external pressure
R. C. Xiao, P. L. Gong, Q. S. Wu +8
A pair of type-II Dirac cones in PdTe was recently predicted by theories and confirmed in experiments, making PdTe the first material that processes both superconductivity…
Observation of Large Topologically Trivial Fermi-Arcs in the Candidate Type-II Weyl Semimetal WTe2
F. Y. Bruno, A. Tamai, Q. S. Wu +13
We report angle-resolved photoemission experiments resolving the distinct electronic structure of the inequivalent top and bottom (001) surfaces of WTe2. On both surfaces, we ident…
