Hallo VASP users and admins,
I would like to use GW energies to compute the RPA absorption spectrum.
By this, I mean that I have already performed a G0W0 calculation on top of HSE03. Now I would like to compare the RPA spectrum (without local fields) obtained with HSE03 and GW.
Since I am working on the perturbative GW approach, I need only to change the energies in the polarizability, not the wavefunctions.
Is there a way to do so? I haven't find any clear discussion on this point.
Thanks a lot.
