ADC-G3W2 reformulates vertex corrections to the GW self-energy as nonperturbative resummations within the ADC framework to guarantee positive semi-definiteness of the self-energy.
Derives static effective Hamiltonians via cRPA and mRPA downfolding with double-counting corrections and compares performance on benzene ground state and bond dissociation curves.
