WebPhonons are quantizations of the normal modes of atomic oscillations in a crystal. We can use DFT and some post-processing software to calculate the vibrational modes of a crystal, calculate the phonon density of states, and integrate that to get the vibrational entropy, enthalpy, and heat capacity of the crystal. Webplot_phonons.py You should get a plot something like the following. To calculate the phonon density of states, generate a mesh.conf file which looks like following: ATOM_NAME = FeSe DIM = 2 2 2 MP=20 20 20 PDOS=1,3 Now we calculate the phonon density of states using the following command. phonopy -p mesh.conf -c FeSe.struct --wien2k e2. iron on transfer paper michaelshttp://phonopy.github.io/phonopy/examples.html iron on transfer paper for wood
