WebJul 6, 2024 · In this work, using compatibility relations, we first list all possible high-symmetry lines (HSLs) that can be nodal lines itself, high-symmetry planes (HSPLs) that can host nodal loops, and HSPLs that are nodal surfaces for all 230 space groups (SGs), with spin-orbit coupling and time-reversal symmetry considered or not. WebMay 27, 2024 · Take a rectangular Brillouin zone as the one depicted below: The center of the brillouin zone is unequivocally marked as Γ. For the other high-symmetry points, it's easy to reconcile in this case - 'X' and 'Y' just represent points on the rectangle along k x an k y.

WebApr 3, 2024 · Since the symmetry-based methods [62, 63] only utilize the symmetry representations at isolated high-symmetry momenta as input, ... Matching of representations between end points of a high-symmetry line. The color indicates C 2x symmetry eigenvalues. (c) Enforced band connectivity due to nonsymmorphic symmetry. First Brillouin zone of FCC lattice, a truncated octahedron, showing symmetry labels for high symmetry lines and points Several points of high symmetry are of special interest – these are called critical points.
