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.
Density is the measure of how much mass is contained in a measured volume, or how much stuff there is in one spot. Clearly, if you have a sponge and a rock that are the same size, there will be more material in the rock, because the sponge has hundreds of holes in the same volume of space.
