“…In our previous works, correlated interactions derived in the UCOM framework, referred to as V UCOM in the following, have proven their merit in a wide range of many-body methods, from ab-initio calculations of light nuclei in the No Core Shell Model [10,11,12] to Hartree-Fock (HF) and HF-based extensions like Many-Body Perturbation Theory [13,14], RPA [15,16], and Second RPA [17]. Since HF-based approaches do not account for pairing correlations, they are expected to work best for closed-shell nuclei.…”
