WebAug 8, 2024 · Determine the points where two consecutive bisectors join, by writing down the equations of their straight lines and making them equal. The points where bisectors cross are your high symmetry points. And this process, repeated for all pairs of vectors in point 2, give you the first Brillouin zone. I got the following: WebAug 11, 2024 · Figure 1. Eigenvalues of the topological Hamiltonian at high symmetry k-points can be labeled by irreps of the little group of the k-point.The gap in the spectral function at ω = 0 causes the eigenvalues to be real. Depending on the sign of the eigenvalue, it is either an R-zero or an L-zero.
