Dear all
I encountered the following error while using EPW v.5.4 to calculate the anisotropic superconducting gap.
I’m using PAW pseudopotentials and my input files are also added below.Although I tried my best to read the source code, I still don’t understand why this error occurs. Any help would be greatly appreciated !
Dear qdhao:
You are encountering the issue with large memory footprint and you need to check my previous post at https://forum.epw-code.org/t/error-in-routine-read-frequencies/817/10 .
Well, this is not related to your issue, but I would suggest you to use norm-conserving pseudopotentials.
Rigorously speaking, both PAW and USPP have issue with the symmetry relation of electron-phonon vertex.
Sincerely,
H. Lee
