Saturation with chiral interactions and consequences for finite nuclei

Understand

We explore the impact of nuclear matter saturation on the properties and systematics of finite nuclei across the nuclear chart.

• Using the ab initio in-medium similarity renormalization group (IM-SRG), we study ground-state energies and charge radii of closed-shell nuclei from $^4$He to $^{78}$Ni, based on a set of low-resolution two- and three-nucleon interactions that predict realistic saturation properties.
• We first investigate in detail the convergence properties of these Hamiltonians with respect to model-space truncations for both two- and three-body interactions.
• We find one particular interaction that reproduces well the ground-state energies of all closed-shell nuclei studied.
