Dear Dr. Lee, Thank you very much for your reply. I greatly appreciate that. After checking the EPW source code more carefully, I find that there are two minus signs missing, which in fact cancel each other in the linewidth calculations. The first minus sign missing is in the Im[Sigma] (Eq. 8, CPC 2...

Dear EPW developers, I have two simple questions concerning the electron self-energy that arises from electron-phonon interaction. I have run a test calculation and obtained something like: ik = 7 coord.: 0.0000000 0.0000000 0.1000000 -----------------------------------------------------------------...

Thank you very much, Dr. Lee.

Dear EPW developers, I know from the EPW documentation that spin polarized calculations are not implemented in EPW. However, both phonon calculations and Wannier90 can handle spin polarized calculations, therefore I am wondering whether each mode-resolved electron_phonon coupling can be considered t...
