Kpoint indexes in Coulomb matrix elements
Posted: Fri Mar 11, 2022 7:51 am
Dear developers,
K-points used in Coulomb matrix elements are in full Brillouin zone, I'm wondering if its indexes and values are the same as kmesh.pl (Wannier90 utility)?
As I see in k_expand.f90 and k_build_up_BZ_tables.f90, Yambo uses k-points in ibz and opens it to bz by multiplying k-points in ibz with some symmetry matrices.
With k-points in ibz having - sign and multiplying procedure to expand, I doubt that k-points' indexes and values are equal to the results of kmesh.pl.
If it's not the same can you help me output kpoints' values?
Best,
Minh
