Can someone tell me the procedure to calculate the dielectric functions by including the excitonic effects using time-dependent Hartree–Fock calculations (TDHF) based on the HSE06 calculations in VASP. I would like to calculate TDHF optics calculations for 2D materials. It would be greatly appreciated if you could tell me the procedure to perform this calculation and the INCAR tags one should use.
Thank you in advance
