In-Medium Similarity Renormalization Group for Nuclear Structure—Applications and Extensions — •Klaus Vobig 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 over a wide mass range.

We employ the IM-SRG for the study of a new generation of consistent interactions derived from chiral effective field theory within the LENPIC collaboration. Focussing on ground-state energies and charge radii for medium-mass nuclei, we study the order-by-order behavior of the chiral expansion.

Furthermore, we present a novel ab initio many-body approach that combines the IM-SRG with Configuration Interaction methods for targeting excited states and open-shell nuclei.
