Anharmonic IFCs

Post by nikhitha79 »

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?
