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.

Hi, Raji!

Obtain dielectric function (depending on frequency) using epsilon.x and find dielectric function value at zero frequency limit.

Sincerely yours,
M. V. Kondrin
