Dear QE users
I'm trying to understand what is the correspondence between the d-orbital
diagonal elements of the occupation matrix and the atomic d-orbitals used as
projectors. I found two responses in the mailing list, but they have
different orbital ordering. I would like to know if the following is
correct:
$$$$$$
atom 4 spin 1
eigenvalues: 0.7294836 0.7306191 0.7326025 0.7629065 0.8283887
eigenvectors
1 0.0000000 0.0000000 -1.0000000 0.0000000 0.0000000
2 0.0000000 -1.0000000 0.0000000 0.0000000 0.0000000
3 -0.0087135 0.0000000 0.0000000 0.9999620 0.0000000
4 0.0000000 0.0000000 0.0000000 0.0000000 -1.0000000
5 -0.9999620 0.0000000 0.0000000 -0.0087135 0.0000000
occupations
0.828 0.000 0.000 0.001 0.000
0.000 0.731 0.000 0.000 0.000
0.000 0.000 0.729 0.000 0.000
0.001 0.000 0.000 0.733 0.000
0.000 0.000 0.000 0.000 0.763
$$$$
.....Do we have this?
z2-r2 / xz / yz / x2-y2 / xy
n 0.8283887 0.7306191 0.7294836 0.7326025 0.7629065
Thanks
Ricardo
