INT S@INT Seminar: "Renormalization group advances for nuclei and strong interaction matter"

Achim Schwenk, TU Darmstadt
Zoom

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.
