Hello, Correct me if I am wrong, but it seems that the issue is related with the interpolated phonon frequencies, and not with the phonon self-energy calculation. Did you run the quadrupole EPW calculation as the initial calculation, with flags: epwwrite = .true. wannierize = .true. or did you run ...

I am currently performing electron–phonon interaction calculations for wurtzite GaN using EPW, and I have encountered an issue related to the Quadrupole correction in the phonon self-energy calculation. As shown in Figure 1 1.png ， when the Quadrupole term is not included, the phonon self-energy cal ...
