1. Ensemble Green's Function Theory for Interacting Electrons with Degenerate Ground States
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : An ensemble Green's function theory for many-electron systems with degenerate ground states, based on the von Neumann density matrix formalism, is proposed. The formalism is constructed without an assumption of an adiabatic connection. An ensemble analogue of Hedin's equations and the GW Approximation (GWA) is constructed. READ MORE
