http://www.nanolab.ece.ufl.edu/document/Phonon%20Dielectric%20Calculation.pdf WebUse “phonopy --dim="2 2 2" -c POSCAR-UC --qpoints="0 0 0" –eigenvectors” to get these. We need phonon frequency at Γ point to calculate the dielectric tensor from lattice contribution. You will get a qpoints.yaml file after using the command. It contains eigenvector for each atom for each phonon frequency. Hf:

WebphonoLAMMPS has been designed to have a very similar python interface to phonopy. For this reason the python objects generated by phonoLAMMPS can be used with phonopy functions. The procedure to obtain the force constants from LAMMPS forces is the following: Loading phonoLAMMPS module from phonolammps import Phonolammps
