The field of ab initio calculations has seen dramatic progress in the past years to access nuclei up to mass number A~100. These advances promise a first principles understanding of the nuclear chart, including electroweak interactions in nuclei that are key for neutrino and astroparticle physics.
A powerful and flexible method that has significantly expanded the ab initio reach is the in-medium similarity renormalization group (IM-SRG). The IM-SRG uses flow equations combined with normal ordering to decouple higher-lying states from a reference state or from low-lying configurations. This decoupling can be adapted flexibly, making it a very versatile many-body method. This talk will discuss recent IM-SRG achievements and outstanding challenges for nuclei, and discuss new results for strong interaction matter.
