[Pw_forum] Frequency Dependent Dielectric Function

[Layla Martin-Samos]

Dear Iwan, take a look at epsilon.x inside PP directory. Be careful,
epsilon.x only implements RPA (Random Phase Approximation) dielectric
function with no local fields effects and without the nonlocal part of the
pseudopotential.

cheers

Layla
