    "abstract": "We propose a framework to construct the ground-state energy and density\nmatrix of an N-electron system by solving selfconsistently a set of\nsingle-particle equations. The method can be viewed as a non-trivial extension\nof the Kohn-Sham scheme (which is embedded as a special case). It is based on\nseparating the Green\u0027s function into a quasi-particle part and a background\npart, and expressing only the background part as a functional of the density\nmatrix. The calculated single-particle energies and wave functions have a clear\nphysical interpretation as quasiparticle energies and orbitals.",
