Abstract: 

DFT is a powerful and versatile method in nuclear structure theory [1]. The predictive power of DFT is tied to the accuracy of the nuclear energy density functional (EDF). Current phenomenological EDFs are rather successful in reproducing stable nuclei, but to overcome their known shortcomings that are visible e.g. when they are applied to nuclei far from the stability valley, new strategies are called for. In this talk, I will describe our approach to constructing EDFs constrained by ab initio calculations of the equation of state (EOS) and the static response of infinite nuclear matter [2,3]. Then, I will show ongoing developments of the ab initio Self-consistent Green’s functions method [4] for the nuclear matter EOS.
