Title: Precision nuclear structure with the in-medium similarity renormalization group

Abstract: Ab initio nuclear structure theory aims to predict the structure of atomic nuclei from “first principles,” employing systematically improvable approximations in the determination of inter-nucleon potentials and in the solution of the many-body Schrödinger equation. Over the past decade, the in-medium similarity renormalization group (IMSRG) has been established as a powerful and flexible method to approaching the many-body problem. I will discuss the developments that have allowed the IMSRG to emerge as a consistent framework for predicting the structure of medium-mass nuclei (closed- and open-shell) and have extended the reach of the method to heavy systems. Recently, we have worked on extending the IMSRG to the next order, the IMSRG(3) with normal-ordered three-body interactions. I will discuss the improved description of the structure neutron-rich calcium isotopes made possible by the IMSRG(3) and what this means for existing discrepancies to experimental trends.
