Contents

In this topic, the density functional theory (DFT) approach will be discussed. The Kohn-Sham equations will be derived and the capabilities of the method. The details of a DFT simulations will be presented. As an application, it will be shown in which way the DFT scheme can be used to generate a classical potential for DNA.
