I could be wrong, but I think the values of the complex momentum matrix
elements in the mommat2 file should be in units of momentum.
In the atomic units (a.u.) system [
https://en.wikipedia.org/wiki/Atomic_units ], I believe the momentum
element values are unitless or dimensionless.
However,
Dear Wien2k users,
Hello, I am currently working on obtaining the transition dipole moments of
ZnO and Sapphire along specific paths in the Brillouin Zone using optic.
I calculated the momentum matrix elements (the ones in case.mommat2) but I
seem to be getting values slightly lower than the ones
