Breakthroughs in our development of nuclear interactions rooted in QCD, many-body methods, and novel AI/machine learning techniques are transforming modern nuclear theory into a true predictive, first-principles discipline. This allows us to now address some of the most exciting questions at the frontiers of nuclear structure, astrophysics, and searches for physics beyond the standard model.
In this talk I will discuss recent advances and highlights of the ab initio valence-space in-medium similarity renormalization group and how these breakthroughs have enabled global converged calculations of essentially all properties of open-shell nuclei to the 208Pb region and beyond. I will focus on key topics in nuclear structure such as predictions of the limits of existence (the proton and neutron driplines), the structure and evolution of magic numbers throughout the chart from energies, radii, spectroscopy, and electromagnetic moments, as well as new results for informing r-process nucleosynthesis simulations in the N=126 region.
