| Abstract | In this lecture, we provide a brief introduction to "beyond DFT" methods for studying excited state properties, optical properties, and transport properties. We discuss how the GW approximation to the self-energy corrects the quasiparticle excitations energies predicted by Kohn-Sham DFT. For optical properties, we discuss the Bethe-Salpeter Equation. We finally provide an example demonstrating the use of the Landauer formalism for exploring transport properties. |
