WebJan 27, 2024 · 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. As an application, we for the first … WebThe frozen phonon method calculates the force constant matrix by displacing each atom in a unit cell and calculating the resulting forces on every other atom. Ideally, this is done for an infinite crystal, and the induced forces between atoms go to zero as the distance between the involved atoms increases.
