[QE-users] TDDFPT imaginary and real parts of the dielectric function.

[Elio Physics]

Dear all,

I have a quick question regarding the dielectric function's TDDFPT expressions of the imaginary (epsinlon_2)and real (epsilon_1) parts.

Is there an explicit dependence  (inversely proportional to) on volume for epsilon_2 like in the Independent particle approximation (IPA)?

What is the relationship between epsilon_2 (IPA) and epsilon_2 (TDDFPT)?
