Learning outcomes

On completion of the course, the student should be able to

  • account for the fundamental background of Density Functional Theory (DFT).
  • explain how electron correlation is defined and how it is approximated within DFT and compare these approximations to other correlated methods.
  • explain the Hohenberg-Kohn theorems and their application.
  • account for the Kohn-Sham equations and density functionals, such as Slater’s X-alpha and the Local Density Approximation (LDA).
  • illustrate the difference between more modern functionals such as the PBE and B3LYP functionals and earlier functionals, such as the LDA functional.
  • identify the areas within computational physics where DFT generally performs well and also areas where the theory fails in predicting properties of bulk materials or molecules.
  • to be able to determine, from a physical context, weather or not the properties of a certain material can be studied by means of DFT or any other correlated method, and if so, select the method which is the more suitable.

Content

Electron correlation, the Perdew-Burke-Ernzerhof functional (PBE), local density approximation (LDA), hybrid functionals (such as B3LYP), Kohn-Sham equations, Hohenberg-Kohn's Theorem, adiabatic connection, exchange correlation hole, exchange interaction, self interaction, functional derivative, Janak's theorem, transition state theory, finite temperature (Mermin) functionals, N-representability and V-representability.
