DESCRIPTION:Speakers: Francesco Marino (Institut für Kernphysik\, Johanne
 s Gutenberg Universität\, Mainz\, Germany)\nIn this talk\, we will presen
 t our work at the interface between density functional theory (DFT) and *a
 b initio* theory. In particular\, we will focus on infinite nuclear matter
 \, that we simulate using a description based on a finite number of nucleo
 ns\, and discuss three research directions [1]:\n1. a new *ab initio* Self
 -consistent Green's function (SCGF) approach\, based on the algebraic diag
 rammatic construction (ADC) approximation scheme that has proved successfu
 l in finite nuclei\, is applied to determine the equation of state (EOS) o
 f nuclear matter using chiral interactions [2]\;\n2. we go beyond homogene
 ous matter\, and present results for nuclear matter perturbed by an extern
 al static potential\, the so-called static response problem [3]\, within t
 he DFT method [4] and\, at a preliminary level\, within Quantum Monte Carl
 o\;\n3. finally\, we present our program aimed at the construction of *ab 
 initio*-based energy density functionals (EDFs) [1\,5]\, and discuss how t
 he static response offers in principle the possibility to gain information
  on the surface terms of the EDF *ab initio*.\n\nReferences:\n[1] F. Marin
