Real part of the electron self energy

[sohamg]

Dear EPW administrators and users,

I would like to compute the real part of the electron self-energy to see its behavior around the Fermi level. I see that it has already been produced using EPW (for example Fig. 5 (a) in https://arxiv.org/pdf/1005.4418.pdf). I find that in src/selfen_elec.f90, the imaginary part is computed but I don't see a straightforward way to output the real part.

I will really appreciate some help. Am I missing something straightforward?

Thanks and regards,
Soham.

Dear Soham,

The real part of the electron-phonon self-energy is printed in the output by default (at least in the most recent version of EPW).

The variable in the routine is called "sigmar_all".

Be aware that this contains only the Fan self-energy (no Debye-Waller term) such that ZPM of the bandgap will not be obtained.

Best,
Samuel

Dear Samuel,

Thanks. I overlooked it.


Sincerely,
Soham.
