I think I have the answer. The subroutine S^-1 is sm1_psi and S only changes if the ion positions change.<br>

Dear all,<br>
<br>
</div>
<div dir="auto" style="direction:ltr;margin:0px;padding:0px;font-family:sans-serif;font-size:11pt;color:black">
ESPRESSO has a subroutine calles s_psi() that applies the S matrix to the wavefunction. Is there a way to apply the inverse of S to the wavefunction?
<br>
<br>
</div>
<div dir="auto" style="direction:ltr;margin:0px;padding:0px;font-family:sans-serif;font-size:11pt;color:black">
Also, is S constant throught the SCF iterations?<br>
<br>

Thanks in advance for any replies.<br>
