WebJun 6, 2024 · The study of phonons is an important part of condensed matter physics. By listening to this unit, we will learn how to perform phonon calculations and then obtain … 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.

WebSetting up a phonopy calculation is similar to settings up a relaxation (or any other workflow supported by FHI-vibes ). To ensure that our physical settings don't change, we will copy the relaxation.in obtained in the previous part of the tutorial to the new working directory and rename it to phonopy.in.

WebNov 19, 2024 · SET UP CALCULATIONS: Create a folder with the desired POSCAR unit cell. Decide on the size of supercell to do calculation on. For example, 2 x 2 x 2. Generally we aim for a supercell that has similar a, b, and c lattice vector lengths. In command line, enter: phonopy -d --dim="2 2 2". This writes out a series of new POSCAR files.
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.
