In my calculation I found out that the one electron wave function are not normalized to unity. I searched through the forum and made some checks and I found out that these is due to the fact that I used Ultrasoft PseudoPotentials. Unfortunately what I have to do with the wave functions is memory and time consuming and is very sensitive to the number of plane waves of the basis set, so I can't use Norm Conserving PseudoPotential. However I need to enter the one electron wave functions in some matrix element calculations and I don't know if I have to normalize them or I have to use them as they are given by the software.</div><div> </div><div>I take this opportunity to wish everyone a Merry
Christmas.</div><div> </div><div>Thank you.</div><div> </div><span><div>Michele Pisarra, PhD Student,</div><div>Dipartimento di Fisica, Università della Calabria</div><div>Via P. Bucci, Cubo 31 C VI piano, 87036, Rende (CS), Italy</div></span></div></body></html>
