So far, no approximations have been made. The density functional formalism, outlined in the previous sections, could in principle reproduce all ground state properties of any complex many-electron system exactly, if the exchange correlation energy Exc was known. Unfortunately, no explicit representation of this functional, that contains all many-body effects, has been found yet. Thus, approximations to Exc have to be used. The most widely used and very successful approximation is the local spin density approximation (LSDA). The underlying idea is very simple. At each point of space Exc is approximated locally by the exchange correlation energy of a homogeneous electron gas with the same electron and magnetization density. Hence, the approximate functional Exc is of the form [...] It is important to note, that εxc is not a functional, but a function of n(r) and So far, no approximations have been made.
