[Pw_forum] electron phonon coupling --> scattering rate

[qe user]

Hi all,

I am hoping to use QE to calculate the scattering rate due to
electron-phonon interactions. I have followed the tutorial wihch calculates
gamma and lambda but would like to know how to use the electron-phonon
matrix elements and Fermi's Golden Rule to calculate the scattering rate,
similarly to below. Is there any functionality in QE that allows for this?

If anybody would be kind enough to help me with any part of this problem
I'd be very grateful.

Many thanks,
