Symmetry-enforced band crossings in tetragonal materials: Dirac and Weyl degeneracies on points, lines, and planes
Moritz M. Hirschmann, Andreas Leonhardt, Berkay Kilic +2
We study the occurrence of symmetry-enforced topological band crossings in tetragonal crystals with strong spin-orbit coupling. By computing the momentum dependence of the symmetry…

Symmetry-enforced band crossings in trigonal materials: Accordion states and Weyl nodal lines
Y. -H. Chan, Berkay Kilic, Moritz M. Hirschmann +4
Nonsymmoprhic symmetries, such as screw rotations or glide reflections, can enforce band crossings within high-symmetry lines or planes of the Brillouin zone. When these band degen…
