  2. 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

  3. 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
