Anharmonic IFCs
Posted: Thu Nov 27, 2025 4:44 am
Dear developers,
I am trying to calculate the eliashberg function for a variety of systems. However, the harmonic approximation often fails in these systems generating negative frequencies. How do I generate higher order IFCs that can later be used with the EPW module to calculate the eliashberg function?
