Abstract

The purpose of this lecture is to illustrate the application of the Tight-Binding method to a simple system and then to introduce the concept of Density Functional Theory. The motivation to mapping from a wavefunction to a density-based description of atomic systems is provided, and the necessary ingredients to do so (two Hohenberg-Kohn Theorems and the Kohn-Sham formalism) is presented.
