phonon group velocity
Posted: Fri Jan 10, 2020 3:52 pm
Dear developers
I need to find the group velocity of phonons due to e-p interactions.
1. Can we use the frequency data in linewidth.phself to evaluate the phonon group velocity using the relation d(omega)/dq?
2. Also can someone please let me know how to calculate the distances among q points and k points in linewidth files of phonon and electron.
Thank you
