Phonopy software

WebDec 2, 2024 · 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. The first step in such a finite displacement scheme is to generate supercells with small 'q' shifts in different directions. WebIn phonopy there is the option to write the eigenvectors to a file. So I assume this is what you need. Be aware that displacement and eigenvectors usually differ by a factor m^1/2. …
