WebPhonon frequencies and eigenvectors are calculated from the dynamical matrices with the specified q -points. For mesh sampling calculation, prepare the following setting file named, e.g., mesh.conf: ATOM_NAME = Si O DIM = 2 2 3 MP = 8 8 8. The density of states (DOS) is plotted by: % phonopy -p mesh.conf. WebVASP contains a module (aedens) which allows for the core charge to be written out from PAW calculations. This module is included in vasp version 4.6.31 08Feb07 and later. By adding the LAECHG=.TRUE. to the INCAR file, the core charge is written to AECCAR0 and the valance charge to AECCAR2.

WebJul 1, 2024 · Bader charge analysis. In Bader's theory of Atoms in Molecules, we partition a molecule into "atoms" which are separated from each other by surfaces of minimum charge density: You can then calculate the partial charges of the "atoms" in the molecule, e.g. H 2 O might yield: A t o m C h a r g e O − 1.150 H + 0.425 H + 0.425.

WebThe CHG file also stores the charge density and has a similar structure, however, CHG does not contain the PAW one-center occupancies and is mainly intended for visualization and post-processing. VASP creates the CHGCAR file by default, but it can be avoided by setting LCHARG = .FALSE. in the INCAR file.
