Phonon Analysis from Molecular Dynamics Data
copied from cf-staging / dynaphopySoftware to calculate crystal microscopic anharmonic properties from molecular dynamics (MD) using the normal-mode-decomposition technique. These properties include the phonon frequency shifts and linewidths, as well as the renormalized force constanst and thermal properties by using quasiparticle theory. This code includes interfaces for MD outputs from VASP and LAMMPS. PHONOPY code is used to obtain harmonic phonon modes.
