Line 4: LDA is the most simple approximation for this functional, it is ''local'' in the sense that the electron exchange and correlation energy at any point of the space is a function of the electron density at that point in space only. The LDA functional is derived from a model assuming that the per-electron exchange-correlation energy at every point in space is equal to the per-electron exchange-correlation energy of a homogeneous electron gas. {{physics-stub}}
