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. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Abdulrafiu.T Raji, PhD (Physics) Department of Physics, College of Science, Engineering & Technology (CSET), University of South Africa (UNISA), Pretoria, South Africa.
