In conjunction with the 'q' shifts (displacements for the supercells, generated by phonopy), this can tell you the nature of the mode. For example, if the eigenvector points in the same direction as the 'q' shift, it is a longitudinal mode.

This calculation is in fact possible (and relatively easy), using nondiagonal supercells, which would only require a supercell of size 48 (containing 96 atoms). Disclaimer: I am an author of the nondiagonal supercell … WebImportant: The supercell used to calculate the MD has to be an integer multiple of the cell used in phonopy calculation. The order of the atoms within the cell has to be kept in both cells to work properly. A convenient way is to use Phonopy to generate the supercell (SPOSCAR) to be used in the MD. $ phonopy -d --dim="2 2 2" east ayrshire for sale

WebOverview. The Phonopy Python package provides a simple interface for extracting vibrational and thermal properties of materials from VASP output. This tutorial shows how to use VASP and Phonopy for phonon density of states, dispersion, and free energy calculations.
