Dear Ricardo Faccio<br>With many thanks for your guidance;<br>but in LDA+U approximation method, the system is considered only with its potential energy(exchange energy) but in strongly correlated electron system the competition between two models of energy(kinetic and potential) is occurred.
<br>In section 4.5.6 this problem is been solved but with any references!<br>Could you send me the references for this issue?<br>best regards<br><br>Message: 22<br>> Date: Tue, 20 Feb 2007 16:28:02 +0330<br>> From: "soran nabavi" <

<br>> <br>> Dear Soran<br>> Wien works with the LDA+U scheme, for studying strong correlated<br>> electrons. Please read the section 4.5.6 of the user guide for more details,<br>> there is described how to use the orbital potentials (in particular the -orb
<br>> options).<br>> Good luck<br>> Ricardo<br>> <br><br><br><br>
