Neutron-rich nuclei provide important insights to nuclear forces and to the nuclear equation of state. Advances in ab initio methods combined with new opportunities with rare isotope beams enable unique explorations of their properties based on nuclear forces applicable over the entire nuclear chart.
In this talk, I will briefly review recent developments in terms of interactions derived from chiral effective field theory and how they impacted ab initio calculations. I will then focus on two novel chiral low-resolution interactions that accurately describe bulk properties from 16O to 208Pb [1]. I will discuss the range of properties that can be reproduced, and in particular highlight how neutron skins are narrowly predicted over all nuclei with interesting sensitivities for the most neutron-rich, experimentally unexplored cases.
