Occupancies and eigenvectors - LDAUPRINT = 2 or 1
Dear VASP user,
By using the "LDAUPRINT = 2 or 1" and considering the onsite coulomb repulsion, the occupancies and eigenvectors for every atom would be printed in OUTCAR file, I know these columns are for different "d" orbitals (here 3d for Ni (dxy-dyz-...)), but, I can not to interpret them, for example below you can find the occupancies and eigenvectors of two different Ni atom in one calculation, I would be thankful if anybody explain me what exactly these data says here and what are the differences between these two Ni atom based on below information.
Cheers,
Salman
