WebThe term "high symmetry" refers to the fact that at such a local point you have more symmetry elements that copy this point onto itself. You need to distinguish direct and reciprocal space though. In your question you mix these up. Take a simple othorhombic crystal with symmetry mm2. WebThe First Brillouin zone of a body-centered cubic lattice, with high symmetry kpoints marked. Note that this is also the Wigner-Seitz cell of a face-centered cubic lattice in real space. …

WebJun 29, 2024 · Topological quantum chemistry theory analysis reveals a twofold band degeneracy without spin-orbit coupling at the high-symmetry and generic k points located at the k z = ± π plane, which is formed by the bands of (A 1 ⊕ B 2) @ 6 g band representations. Since the compounds studied here have been already experimentally synthesized, the ... WebNov 11, 2024 · I have implemented a function that gives the high-symmetry k path for an arbitrary 3D lattice, where the k path is equivalent to the one that one would get for the standardized primitive lattice.

WebSep 26, 2024 · As you already state that you can not use automatic k-point generation, the solution is: Identify the crystal symmetry you are working on. Look for the Brillouin zones of that symmetry. Select the high symmetry points for the path. Generate the k-point between each symmetry points. Take o look here about how to accomplish these tasks.
