Dear Wien2k users,<br><div class="gmail_quote"><br><p>We have performed total energy calculation for a layered Ti oxide within lda+u using both sic and amf versions. The compound is of trigonal symmetry and only the oxygen position is not fixed along z. Varying the latter we find that the minimum of the energy curve is not where the forces are close to zero. This doesn't happen if we consider a mere LSDA functional: forces and total energies are consistent.<br>
We are quite puzzled by these results and wonder if you could give us some insight.</p>
<p>Thanks & best regards</p><p>Tulika Maitra</p><p><br></p></div>
