Dear community,
I need to calculate electronic and ionic contribution to the static dielectric tensor - similar to what is done in VASP as described here vasp.at/wiki/index.php/LEPSILON . Do I understand correctly that in epsr.dat file, which we obtain after a calculation with epsilon.x, three values at zero frequency correspond to the diagonal elements of the static dielectric tensor? However, even if is true, how can I obtain electronic/ionic contributions?
Thanks in advance,
Anton
P.S. Sorry for my first two e-mails, which were detected as SPAM, this occured because I put a complete URL to the VASP website.
