Description of Electron Ensembletic current density, at least without spin-orbit coupling. The ensemble properties are reasonably described by the grand canonical ensemble, since it allows for particle and energy exchange. Arbitrary numbers of electrons and temperatures of the electron gas can be studied.

Exchange and Correlationatrices. The two-particle one obeys a sum rule that describes classical Hartree and quantum-mechanical exchange-correlation contributions to the electron-electron interaction. It is directly related to the pair correlation and van Hove correlation function.

The differences of matrix elements of the GW self-energy and the exchange-correlation potential may be further approximated. As most simplified approach the description of the quasiparticle effects by a scissors operator is derived.
