WebDec 2, 2024 · 1 Answer. 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. WebJul 26, 2024 · The primitive cell is passed to phonopy, which constructs super cell systems with small atomic displacements. A LAMMPS calculation is performed on the displaced systems to evaluate the atomic forces on each atom without relaxing. The measured atomic forces are then passed back to phonopy, which computes force constants for the system. canon selphy 780 treiber
