The use of Green's Functions in Quantum Chemistry

Modern quantum chemical calculations commonly use wave function based models or densitry functionaltheory (DFT). Using Green’s functions is an approach that has not been explored much, and is one thathas only been explored relatively recently, with older examples being useful, but limited in scope. Theuse of Green’s functions in literature, historically and contemporary, is outlined and explored, with afocus on the self-consistent second order Green’s function (GF2), as well as the GW-approximation.
