Phonopy fatband
WebJul 8, 2024 · When phonopy (or any similar calculation technique) finds displacements in the cell based on symmetry, the idea is to see how the displacement of certain ions affects the forces on every ion within the cell. We must then take care that the displaced ions don't affect themselves i.e. the effect of their displacement doesn't interact with itself. http://grandcentral.apam.columbia.edu:5555/documentation/phonopy/phonopy.html

WebFatbands with spin-orbit coupling A recent question touched on the case of fatband representation when spin-orbit coupling is included in the calculation ( lspinorb = .true.). I assumed that this would be straightforward and indeed there is no problem up to the last step, where plotband.x should read the band energies and projections. WebAug 9, 2024 · 4) Run $ python3 extract_vectors_phonopy.py band.yaml POSCAR.vesta. Here POSCAR.vesta is the VESTA file of the primitive positions of atoms used in the initial SCF calculation, not the supercell from Phonopy.
