hi there,

The LOPTICS gives the plasma frequency and the dielectric function (DF). My question is the following:

Is the plasma frequency (intraband) included automatically in the DF? Or should it be included afterwards for the full response of the system.

E.g. is the real part of the dielectric function already given in the OUTCAR as:

eps_real(w) = 1 - w_p^2/w^2 + eps_real(w)

thanks!
