Dear Wannier user,<br><br>If by MLWF energies you mean the <b>on-site energies :</b> <wn|H|wn> where |wn> is<br>a MLWF and H the total Hamiltonian, and by hopping integrals you mean the following<br>matrix elements : <wn|Hwm>, where |wn> and |wm> are 2 MLWFs then what you're<br>
looking for is the Hamiltonian matrix expressed in the MLWF basis. There is an option<br>in the Wannier input file (the *.win file) that you can use, called "<b>hr_plot = .true.</b>". This<br>option will ask the Wannier90 code to print the Hamiltonian matrix in the MLWF basis<br>
to a file called "<b>seedname_hr.dat</b>". You can look at this in the Wannier90 user guide<br>part <b>2.9.18.</b><br><br>You have to know what is the format of this file, so you should look at part <b>7.18 </b>of the user<br>
guide.<br><br>Good luck!<br><br>Nicolas Poilvert<br><br><div class="gmail_quote">2009/4/2 boulfelfel salah eddine <span dir="ltr"><<a href="mailto:boulfelfel_salaheddine@yahoo.fr">boulfelfel_salaheddine@yahoo.fr</a>></span><br>

Hello everybody,<br><br>I've a simple question. Does anybody knows how to calculate (or extract) MLWFs energies (at a given k point) and the corresponding hopping integrals using the wannier90 code.<br>I've been through the manual but I could not figure it ?<br>
<br>Your help is very appreciated and acknowledged in advance.<br><br>Cheers.<br><br><br>salah <br><br></td></tr></tbody></table><br>
