[QE-users] Renormalized band energies from the postahc.x code

[Lorenzo Paulatto]

> I am attempting to compare PbTe band structure at 0K and 300K using the postahc.x code. The code does print the renormalized self-energies (Example 19 in the PHONON package) but does it store the EPI-renormalized band energies anywhere?

I'm not familiar with this code, but it should be enough to add the 
imaginary part of the self-energy (which is usually negative) to the 
unperturbed phonon frequency to get the renormalized one.
