“…This is achieved by combining aspects of both density functional theory (DFT) [28][29][30][31] and effective field theory (EFT) [32][33][34]. In a DFT formulation of the relativistic nuclear many-body problem, the central object is an energy functional of scalar and vector densities (or more generally, vector four-currents).…”

“…As for the HK theorem, however, the problem of radiative corrections has not been addressed until recently [9]. Thus, in the following, we briefly summarize the KS Although the functional dependence of T, on j p is not known explicitly, T , can be expressed exactly in terms of the single-particle four spinors p,,(x) resulting from a given local potential:…”

“…On the other hand, UV divergencies that result from the perturbative treatment of the interaction between electrons and photons as well as the external potential show up in both the ground-state energy and the ground-state four current. These divergencies can be taken care of by the standard renormalization procedure of quantum field theory (applied to ground-state energies and four currents-see, e.g., [9]), the main point being that all counterterms required to keep the ground-state energy and four current finite are completely determined by specification of V p and do not explicitly depend on the ground state Iq) corresponding to V p . This then allows one to use the familiar nonrelativistic scheme [4] for the proof of the HK theorem also in the relativistic situation where any serious proof must be based on renormalized quantities (for details, see [ 9 ] ) .…”
