Hartree-Fock-Bogoliubov Calculations in the UCOM Framework

With the advent of new radioactive beam facilities like FAIR, the structure of exotic nuclei far beyond the valley of stability can be probed experimentally, providing a strong motivation for theoretical studies using ab initio approaches and interactions which provide a stringent link to QCD as the fundamental theory of the strong interaction. To this end, we apply second-generation VUCOM interactions [1] derived from the realistic AV18 interaction for the description of open-shell nuclei in a HartreeFock-Bogoliubov framework. To disentangle the effects of the particle-hole (ph) and particle-particle (pp) channels, we first use VUCOM as a pairing force in conjunction with the Gogny D1S interaction providing the ph-mean-field. In Fig. 1, the resulting gaps ∆μ of the canonical state with the lowest quasiparticle energy Eμ = √
