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. WebThe phonon entropy is calculated directly by phonopy using the harmonic approximation, i.e. adding the harmonic entropies for each of the modes in your system. This can be done from a few VASP...
