Being probably deep below the gap or Fermi level, d states are not easy to perturb and the linear-response approach implemented in hp.x <br /></div><div>does not work for these cases. Unless one lifts them up (e.g., with a sufficiently high Hubbard_alpha) closer to the edge of the valence band preliminarily. But of course this might corresponds to a significant perturbation of the electronic structure of the system.</div><div><br /></div><div>Best regards,</div><div><br /></div><div>Matteo</div><div><br /></div><br /><div class="f13ca48719c8a60033905b23b39675agmail_quote"><div class="334d7d341e3233c5b27ca91297445127gmail_attr" dir="ltr">Il giorno mer 31 mar 2021 alle ore 21:11 Sergey Lisenkov <<a href="mailto:proffess@yandex.ru" target="_blank">proffess@yandex.ru</a>> ha scritto:<br /></div><blockquote class="f13ca48719c8a60033905b23b39675agmail_quote" style="border-left-color:rgb( 204 , 204 , 204 );border-left-style:solid;border-left-width:1px;margin:0px 0px 0px 0.8ex;padding-left:1ex"><div>Dear users,</div><div> </div><div>I calculated U correction for Cd (Cd based MOF), using HP code (version 6.7, ONCVPS pseudopotentials).</div><div> </div><div>If I use "ortho-atomic" projection type, then calculated U=42 eV </div><div>if I use "atomic" projection type, then calculated U=71 eV</div><div> </div><div>these results do not depend on nq mesh.</div><div> </div><div>Those are, obviously wrong values and I'm trying to understand why.
