Phonopy phonon band
WebAug 5, 2024 · 5. I have observed in research papers that the k-path chosen for electronic band structure and for phonon band structure to be different. I am currently using VASPKIT in order to obtain the path for electronic calculation. But how do I obtain the one for phonon. I think they should be same, but why do some articles use different path.

There are two major techniques used to model phonon interactions - The frozen phonon method and density functional perturbation theory (DFPT). Phonopy is used to carry out calculations in the frozen phonon scheme. ProfM does a fantastic job delineating the differences between the two methods here.
