Dear all,<br><br>I am doing a test on the WANNIER90. The system is very simple, GaAs, which is the same as EXAMPLE01. I did the wannier calculations after SCF, NSCF and pw2wan. For the wannier orbitals, I want to interplate 8 for which the initial projection is based on Ga:l=0;l=1 and As:l=0;l=1. However, the final result of $NAME_hr.dat shows that the wannier orbitals are nonorthogonal on the same site because the overlap matrix has non-zero elements among wannier orbitals either on the Ga or on the As. Is there anything wrong with my Calculation? Any suggestion will be appreciated.<br>
<br>Thanks a lot.<br><br>Best regards,<br><br>Mithra Chan<br clear="all"><br>-- <br>Dr. Mithra Chan,<br>Department of Physics, National University of Singapore, Singapore<br><a href="mailto:chan.mithra@gmail.com">chan.mithra@gmail.com</a><br>
