[QE-users] Ferromagnetic Superconductivity in QE

Hello,

I recently began implementing the PHonon code to calculate electron-phonon
coupling, from which the superconducting critical temperature is predicted.
One compound of interest is ferromagnetic, for which the conventional BCS
theory is insufficient. I am able to include spin-polarization in the
computation of phonon dispersions, electron-phonon coupling interaction
coefficients, and critical temperature. However, are these results directly
meaningful for the case of ferromagnetic superconductivity? In other words,
are the effects of spin-polarization explicitly included in the calculation
of electron-phonon coupling to accurately describe the physics occurring in
ferromagnetic superconductors?

Sincerely,
Nathan
