[QE-users] RPA 'epsilon.x' for dielectric constants?

[Raji Abdulrafiu]

Dear colleagues,

My question concerns calculating the dielectric constants
(static/macroscopic) of solids using the RPA approximation.
I want to find out however if I may use the epsilon.x executable for this.

It was suggested that one sets the frequency to zero and look at the static
dielectric function. My question therefore is where do I do this?. Perhaps
in the epsilon.f90 code. If yes, where exactly in the code? I will
appreciate any lead on this, as it doesn't appear that it would be in the
epsilon input file.

Thank you very much for your time.
