Ab-initio approaches to nuclear structure

The No-Core Shell Model is a powerful method to calculate nuclear properties starting from internucleon interactions. As in the traditional Shell Model, effective interactions have to be constructed for the model space where the Schroedinger equation is solved. I discuss how this can be done systematically and consistently with the underlying theory of strong interactions, QCD, using effective...

Ab-initio approaches to nuclear structure

The talk discusses recently achieved proof-of-principle calculation based on Gorkov-Green's function theory. The method allows first principle calculations of truly open shell, semi-magic, nuclei and has been applied successfully up to Ni-78 with soft low-momenutm interactions. The inclusion of three-nucleon forces has also been demonstrated by calculations within the Green's function...

Ab-initio approaches to nuclear structure

The transition from descriptions of nuclear-wave functions in terms of A nucleons (fermions) toward those in terms of n < A composite clusters as e.g. particles (bosons) is far from being obvious. However, it represents a very interesting challenge which can help to point out states in which clustering is expected to be strongly dominant as in so-called condensate state, a typical...
