In-Medium Similarity Renormalization Group for Nuclei — •Klaus Vobig, Sven Binder, and Robert Roth — Institut für Kernphysik, Technische Universität Darmstadt

The In-Medium Similarity Renormalization Group (IM-SRG) is a very flexible ab initio many-body method for the calculation of nuclear structure observables through an efficient SRG flow-equation approach.

Based on nucleon-nucleon and three-nucleon interactions derived from chiral effective field theory that are transformed through the free-space SRG for improving the convergence behavior, we use the IM-SRG for systematic studies of closed-shell nuclei up to ¹³²Sn. Comparisons with the most advanced Coupled Cluster and No-Core Shell Model calculations are used to validate this new many-body approach. We explore extensions of the IM-SRG framework to other observables and excited states.
