Is It possible to calculate Dielectric Function in time-dependent density functional perturbation theory (TDDFPT)?

01 July 2024 0 8K Report

Usually, Ultra-soft pseudopotentials (USPP) do not work with epsilon.x code. Therefore, I am trying to use TDDFPT. Though it provides absorption spectra, I am confused whether it is possible to get the Real and Imaginary Part of the Dielectric Function or not.
