Applied Physics Seminar: "Computational Green's function methods applied to solids and molecules"

Abstract: We present a detailed discussion of Green's function methods as applied to both quantum chemistry and condensed matter. Subsequently, we discuss the self-energy embedding theory (SEET) which is a Green's function quantum embedding scheme allowing us to describe a chosen subsystem very accurately while keeping the description of the environment at a lower cost. We apply SEET to solid and molecular examples where commonly our chosen subsystem is made out of a set of strongly correlated orbitals while the weakly correlated orbitals constitute an environment.
