WebJan 27, 2024 · Download PDF Abstract: The irreducible representation of band structure is important for physical properties. Based on phonopy and recently developed SpaceGroupIrep package, we developed a package PhononIrep, which can get the band irreducible representation for arbitrary $\boldsymbol{k}$ point at first-principles level. WebMar 15, 2024 · CHAPTERTHREEWORK FLOWWork flow of phonopy is shown schematically. There are two ways to calculate, (1) atomic forces from finite displace-ments and (2) given force constants. You can choose one of them. Forces on atoms or force constants are calculatedby your favorite calculator (shown by the diamonds in the work flow).
