WebDec 2, 2024 · Phonopy can give you the eigenvectors of the modes. 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.

http://phonopy.github.io/phonopy/symmetry.html WebWhen lattice parameters of unit cell (set by POSCAR) are the column vectors of a u, b u, and c u, those of supercell, a p, b p , c p, are determined by, ( a p b p c p) = ( a u b u c u) M _ p. M p is a change of basis matrix and so M p − 1 must be an integer matrix.
