PAW potential
Posted: Thu Jul 31, 2008 9:38 pm
Dear VASP experts,
I'm trying to understand the format of PAW potential files as part of study, rather than simply using them blindly. I would really appreciate you if any of you can explain the format of the PAW potential files, aside from top header lines .
For instance, I can find the following headers, but have no idea what grids
are used of what steps ,intervals, k-space or r-space, etc.
I was especially wondering about nonlocal parts of potentials, their orders, their grids.
(1) Error from kinetic energy argument (eV)
(2) local part
(3) atomic pseudo charge-density
(4)Non local Part: Reciprocal Space Part
Real Space Part
(5) PAW radial sets
augmentation charges (non sperical)
uccopancies in atom
grid
(6) aepotential
(7) core charge-density
(8) kinetic energy-density
(9) pspotential
(10)core charge-density (pseudized)
(11)pseudo wavefunction
(12) ae wavefunction
Thanks in advance,
Jan
