In Density Functional Theory, the electron density is the quantity of interest. In Wavefunction Functional Theory, the wave function is the quantity of interest. Very Good Reference: R.G. Parr and W. Yang, Density-Functional Theory, (Oxford Press, 1989). East Carolina University
Density Functional Theory (Hohenberg-Kohn 1964) The ground state energy E of an N-electron system is a functional of the electronic density and it is a minimum when evaluated with the exact ground state density. Minimize E[,] with respect to variations in subject to the constraint of charge conservation, N= d { E[,] - d } = 0 The resulting Euler-Lagrange equation is E / = East Carolina University
