I am performing an in-house code to obtain the static dielectric constant when q->0 using ultrasoft pseudopotentials, but I can not obtain the term<n,k| [Vnl,r] |l,k+q> of the <span style="font-family: Calibri, Helvetica, sans-serif; background-color: rgb(255, 255, 255); display: inline !important">oscillator
strength matrix element <n,k| exp(i(q+K)·r) |l,k+q>,</span> because I do not know how to extract this information from the calculations. The question is: ¿Where can I find the information about the non-local part of the pseudopotential from calculations using
Quantum Espresso? or ¿Can I obtain this information directly from the .UPF file?</div>
