*Density Functional Theory* DFT is a reformulation of Hartree-Fock in terms of a joint electron density

- ,

which introduces a new contribution (from Slater determinants) to the total energy named *exchange-correlation energy* . The dependence of on is unknown and DFT thus relies on predictions of EC based on Hartree-Fock and thus DFT has the same limitations as Hartree-Fock, albeit at (somewhat) smaller computational cost.
