In these notes I have given a personally flavored exposé of static density- functional theory (DFT). I have started from standard many-body physics at a very  

1.7 What Can't DFT Do?. 1.8 Density Functional Theory in Other Fields. 1.9 How To Approach This Book (Revisited). Density functional theory (DFT) is a quantum-mechanical (QM) method used in chemistry and physics to calculate the electronic structure of atoms, molecules and solids. It has been very popular in computational solid-state physics since the 1970s. Density functional theory (DFT) has been used in many fields of the physical sciences, but none so successfully as in the solid state.

This This theory combines hybrid density functional theory with MP2 semi-empirically. The B2PLYP functional, which is an example of this approximation, can be specified as: mp2 freeze atomic end dft xc HFexch 0.53 becke88 0.47 lyp 0.73 mp2 0.27 dftmp2 end For details of the theory, please see the following reference: Density Functional Theory The density functional theory (DFT) treats the electron density as the central variable rather than the many-body wavefunction. This conceptual difference leads to a remarkable reduction in difficulty: the density is a function of three variables, i.e.

Many workshops and schools teach how to run a specific code. The purpose of this school is to teach the theory behind DFT. Lectures will be pedagogical and

Density functional theory

Density functional theory (DFT) is one of the most widely used methods for ab initio calculations of the structure of atoms, molecules, crystals, surfaces, and their interactions. Unfortunately, the customary introduction to DFT is often considered too lengthy to be included in various curricula.
