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.
By definition, density is the. mass of an object divided by its volume (D=M/V). Although it is easy to determine the mass of an. object using scales, it is very difficult to determine the volume of an object that has an irregular. shape such as the human body. It is possible to measure the volume of the human body by.
