Annihilation of Weyl points at NW = 2 over multi-fold supercells of even N. a Unit Chern number 3D CI. b, c, d Increasing Chern numbers C according to the relation C = N/2. Calculations performed on 1D supercells (1, 1, N) with modulation parameter rm = r0/20 and WL on selected planes for kz/2π = 0.3. Source data are provided as a Source Data file.
