WebPhonopy is A phonon calculation toolbox and toolkit Easily installed on Ubuntu (or recent distributions) – Currently Windows and Mac OS X are out of consideration. – Windows and Mac users are encouraged to boot Ubuntu on a virtual machine (e.g. VMware, Virtualbox) Phonopy requires force calculators, e.g., it work togather with first-principles calculations, … WebDec 10, 2024 · The modulation in phonopy corresponds to the value of one phonon mode in the summation. How to understand this is up to you. As written by Aldo, eigenvector element itself is not given in the distance, which is normalized or can be understood coefficients of transformation.
