Screened extended Koopmans' theorem: photoemission at weak and strong correlation
S. Di Sabatino, J. Koskelo, J. A. Berger +1
By introducing electron screening in the extended Koopmans' theorem we correctly describe the band gap opening in weakly as well as strongly correlated systems. We show this by app…

Introducing screening in one-body density matrix functionals: impact on the Extended Koopmans' Theorem's charged excitations of model systems
S. Di Sabatino, J. Koskelo, J. A. Berger +1
In this work we get insight into the impact of reduced density matrix functionals on the quality of removal/addition energies obtained using the Extended Koopmans' Theorem (EKT). W…
