Hence the name density functional theory comes from the use of functionals of the electron density. DFT is among the most popular and versatile methods available in condensed-matter physics, computational physics, and computational chemistry.n general, density functional theory finds increasingly broad application in the chemical and material sciences for the interpretation and prediction of complex system behavior at an atomic scale.
Introduction. The purpose of this site is to explain in a non-mathematical way what density functional theory is and what it is used for. I hope to familiarise the reader with the syntax of solid state theory and give a basic understanding of the related topics.n this case the total ground state energy of a many-electron system is a functional of the density. So, if we know the electron density functional, we know the total energy of our system. By focusing on the electron density it is possible to derive an effective one-electron-type Schroedinger schrÃ¶dinger. equation
