[Pw_forum] Electron Phonon coupling

[Manish Jain]

Hi Eyvaz,

Thanks for your response. I am a bit confused though.

I was talking about calculating the electron phonon coupling matrix 
elements... As I understand,
in semiconductors and insulators have these couplings. What is absent is the 
line width due to
electron phonon scattering because of this because there are no states 
available at the fermi level.
All I wanted to confirm was that I can calculate the coupling matrix 
elements with pwscf for
insulators. I understand that taking it further and calculating the 
linewidths is not possible.

Thanks,
Manish
