Dear QE users<br>
<br>
I'm trying to understand what is the correspondence between the d-orbital<br>
diagonal elements of the occupation matrix and the atomic d-orbitals used as<br>
projectors. I found two responses in the mailing list, but they have<br>
different orbital ordering. I would like to know if the following is<br>
correct:<br>
<br>
<br>
$$$$$$<br>
atom 4 spin 1<br>
eigenvalues: 0.7294836 0.7306191 0.7326025 0.7629065 0.8283887<br>
eigenvectors<br>
1 0.0000000 0.0000000 -1.0000000 0.0000000 0.0000000<br>

3 -0.0087135 0.0000000 0.0000000 0.9999620 0.0000000<br>

<br>
.....Do we have this?<br>
z2-r2 / xz / yz / x2-y2 / xy<br></blockquote><div><br>this is how the basis of d states is ordered (growing |m| from 0 to 2).<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
n 0.8283887 0.7306191 0.7294836 0.7326025 0.7629065<br></blockquote><div><br>In this particular case the matrix is diagonal so the eigenvectors coincide with the basis vectors. <br>Yes, 0.7294 is the occupation of yz, 0.7306 of xz, 0.7326 of x2-y2, etc.<br>
as can be read from the composition of the eigenvectors. <br></div><div><br>Matteo<br><br> <br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Thanks<br>
