Density Functional Theory

Paper details:

Density Function Theory(DFT) Literature review. Please go into detail about DFT and its formation. (Thomas fermi Theory) (Hohenberg-kohn Theorms) (Kohn-sham) Using Math along the way Go into detail about the DFT approximation techniques. These techniques approximate exchange correlation. The 2 main ones are LDA and GGA. GGA is built off LDA and is very important. Use math in explanations Go into the self interaction error, and why it occurs in the approximation techniques. Also go into the ‘Exchange Hole’ and how its used. All 3 attached papers should have all the information that is need, however find additional sources where possible Please use Latex if possible, and provide the code as well as pdf.
