I am studying an organic complex with rare earth<br>
metals (only collinear case, without spin-orbit coupling at the moment).<br>
Some articles, as for example:<br>
<br>
PRB 75, <a href="tel:045114" value="+39045114" target="_blank">045114</a> (2007)<br>
ACS Nano, 2014, 8 (5), pp 4662–4671<br>
<br>
indicate that for a correct description of the rare-earth compounds<br>
could be necessary to apply the Hubbard-U corrections both on the f and<br>
d electrons of the same atom. If I have understood correctly, now the pw.x code can apply<br>
the Hubbard correction only on the electrons with the maximum l of each<br>
atomic species (for example, in the rare-earths case the f electrons)<br>
<br>
In my output is written the line<br>
<br>
"full LDA+U calculation, Hubbard_lmax = 3"<br>
<br>
I would like to know if it is possible to modify the code in order to<br>
enable the Hubbard corrections separately, both on the d and f electrons<br>
(with different values of U and J, overall 4 parameters).<br>
<br>
Approximately, how much effort would require such change ?<br>
<br>
<br>
Thanks for any help,<br>
Regards<br>
<br>
