Testing the GFCCSD impurity solver on real materials within the self-energy embedding theory framework
Chia-Nan Yeh, Avijit Shee, Sergei Iskakov +1
We apply the Green's function coupled cluster singles and doubles (GFCCSD) impurity solver to realistic impurity problems arising for strongly correlated solids within the self-ene…

Ab-Initio self-energy embedding for the photoemission spectra of NiO and MnO
Sergei Iskakov, Chia-Nan Yeh, Emanuel Gull +1
The accurate ab-initio simulation of periodic solids with strong correlations is one of the grand challenges of condensed matter. While mature methods exist for weakly correlated s…
