The density functional theory of superconductivity is extended to triplet superconductors and superfluid helium 3. We prove a Hohenberg᎐Kohn-type theorem for these systems and derive effective single-particle equations. The latter include exchange and correlations in a formally exact way and allow the treatment of both electronic and phonon-induced superconductivity. The relation of this approach to the Bogolubov᎐de Gennes mean-field theory and to phenomenological theories based on Ginzburg᎐Landau functionals is discussed.

We present an analysis of local or semilocal density functionals for the Ž exchange᎐correlation energy by decomposing them into their gradients r local Seitz s . Ž . Ž . radius , relative spin polarization , and s reduced density gradient . We explain the numerical method pertaining to this kind of
We generalize hybrid density functional theory to finite temperatures. We find that the internal potential generated by the orbital functionals leads to complications in the statistical mechanics of the reference system and the self-consistent procedure to obtain the density.
