| Popis: | Two recently proposed exchange-correlation functionals describing the superconducting phase of matter are reviewed and further explored: Whereas the first is a generalization of the local density approximation dealing with purely electronic correlations, the second is a functional derived from Kohn–Sham perturbation theory that includes electronic and phononic correlations on the same footing. Superconducting properties of simple metals obtained with the latter functional agree rather well with experimental results. © 2004 Wiley Periodicals, Inc. Int J Quantum Chem, 2004 |
