Abstract
Important consequences of short-range correlations (SRC) in nuclei are illustrated with several examples. First, the one-body momentum distribution in isospin asymmetric nuclear matter, with special emphasis on its components at high momentum is considered. Explicit calculations for finite neutron-proton asymmetry, based on the ab initio self-consistent Green's function approach, elucidate the isospin dependence of SRC in neutron-rich systems. High-momentum components are determined by the density of each sub-species and a new asymmetry scaling of high-momentum components is presented for different realistic nucleon-nucleon interactions. Second, the influence of SRC on the spectral distribution of neutrons is incorporated in the solution of the gap equation for the 3P2-3F2 coupled channel in pure neutron matter at high density. The gap in this channel is strongly suppressed by these correlations but does not vanish. Long-range correlations (LRC) representing polarization terms have a small anti screening effect once SRC are included. Maximum gaps around 0.1 to 0.2 MeV at most with a small dependence on the hardness of the interaction are obtained. Finally, by employing the dispersive optical model (DOM) the role of SRC are incorporated by constraining the nucleon self-energy for ${}^{40}$Ca and ${}^{48}$Ca to generate all available experimental data related to the nucleon single-particle propagator. These data include $(e,e'p)$ results for high-momentum knockout obtained at Jefferson Lab. The role of SRC in determining the properties of Ca nuclei is clarified and results for the predicted neutron skin in ${}^{48}$Ca presented.
