Dear Alex and kind users,

I have a stupid question: in the calculation of dielectric constants and phonon frequency, typing “amset phonon-frequency”, amset tells me the effective frequency and corresponding weight. What is the relationship between this effective phonon frequency and pop_frequency in the POP scattering_type? As a fact, the pop_frequency is the highest optical phonon frequency at the Gamma point. Could you please give me some suggestions? I want to involve the POP in my calculation.

Thanks a lot!

Best wishes,

Zhibin
