WebMay 28, 2024 · Using the classification of symmetry-enforced band crossings, we perform an extensive database search for candidate materials with tetragonal space groups. Notably, we find that Ba5In4Bi5 and NaSn5 exhibit twofold and fourfold Weyl nodal lines, respectively, which cross the Fermi energy.
