Dear exciting users,
I’m wondering if it is possible to use hybrid functionals for GW in exciting (as an improved KS initial guess).
I tested HSE06 for the groundstate calculation but noticed that in the G0W0 run on top, even though I set do=“skip” in the groundstate element and keep doing everything just like for GGA, the code uses ngridk instead of gw/ngridq and gs/nempty instead of gw/nempty.
Is there anything one has to do differently for hybrids compared to e.g. GGA_PBE ?
I’d appreciate any comment on this, thank you.
