Symmetry of k-points and velocities

Dear EPW users and developers, When I calculated the electron-phonon coupling of Si (space group 227), I used "vme = wannier" in EPW to calculate the energy, electron linewidth, and velocity of the k-point in the full BZ. I encountered two problems related to symmetry: One is that between symmetry ...

Re: Electron linewidth of symmetrically degenerated kpoints

Dear Samuel, Thanks for your reply! I would like to ask another question. When I calculated the electron-phonon coupling of Si (space group 227), I used "vme = wannier" in EPW to calculate the energy, electron linewidth, and velocity of the k-point in the full BZ. In addition to the problem of ...
