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.
Structural-functional theory, or structural functionalism, views society as a system of functional and interconnected units that work together as a whole to produce a state of stability and order. Because of their interconnectedness, the individual units of society can affect each other.
