The Variety of Finite Fermion Systems and Their Basic Properties,ons, and protons, is half-integer (in units of .), otherwise they are bosons. There are a few other bosonic particles in nature, especially the particles mediating elementary interactions but, apart from exceptions, most assemblies of massive particles are built from fermions.

Coherent Two-Body Correlations, typical excitation energies of the system, the latter being easily quantified by the HOMO–LUMO gap . We have learned in Chap. 3 that fermion systems very much prefer situations with a large HOMO–LUMO gap which keeps correlation effects low. We have also seen that such a favorable situation is not necessarily given from the outset.

Density Functional Theory,imple Hartree level. Such effective approaches usually constitute a large step forward to more self-consistent modeling. The formally sound way to formulate such effective theories proceeds through energy-density functionals as a starting point.
