EPW Forum

Dear all I have a simple question about the electron-phonon coupling at Gamma point. In inhomogeneous systems, for example layered materials, the phonon frequencies and the electron-phonon coupling at Gamma depend from the direction where they are calculated. How this direction is decided in EPW ...

Dear EPW developpers I have a question on the Electron-Phonon self-energy (for the electrons). With EPW it is very easy to get the imaginary part of the self-energy, but I image that for the real one the story is more complicated because it requires a sum on many conduction bands. I would like to ...
