order of occupancies in density matrix
Hi,
I am doing LDA+U calculation for electronic structure of Ni-doped corundum Cr2O3(hexagonal cell) using tetrahedron method. The following is density matrix on Ni atom. There are 10 lines data for occupancies of Ni d orbital. Could anyone explain to me the order of these occupancies? Are they just organized from small to large?
Also, the last occupancy is greater than one. How to interpret this in this LDA+U with a PAW psedopotential?
THANKS!
