I would like to solve isotropic Eliashberg equations to get energy gaps using some specific Eliashberg spectral function a2f. I don't need to calculate phonon spectrum. Are there any easy way to implement it? If there is, how to set up?

Thanks a lot.

Hi,

This is already implemented in the code. You can take a look at the epw_iso.in and epw_iso_real.in in qe-6.1/EPW/tests/Inputs/t05

Dear Roxana,

Would you please be more specific on how to do this? Like where should the spectral function go? How to change epw_iso.in?
Thanks very much.

Best,

Hi,

If you already have the Eliashberg spectral function you can use liso together with fial2f variable (their description can be found athttp://epw.org.uk/Documentation/Inputs).

You can make the following changes in the epw_iso.in

ep_coupling = .false.
ephwrite = .false.
fial2f = 'file for eliashberg spectral function'
