Open-Shell Nuclei from No-Core Shell Model with Perturbative Improvement
Alexander Tichai, Eskendr Gebrerufael, Klaus Vobig +1
We introduce a hybrid many-body approach that combines the flexibility of the No-Core Shell Model (NCSM) with the efficiency of Multi-Configurational Perturbation Theory (MCPT) to…
Ab Initio Description of Open-Shell Nuclei: Merging No-Core Shell Model and In-Medium Similarity Renormalization Group
Eskendr Gebrerufael, Klaus Vobig, Heiko Hergert +1
We merge two successful ab initio nuclear-structure methods, the no-core shell model (NCSM) and the multi-reference in-medium similarity renormalization group (IM-SRG) to define a…
Open-Shell Nuclei and Excited States from Multi-Reference Normal-Ordered Hamiltonians
Eskendr Gebrerufael, Angelo Calci, Robert Roth
We discuss the approximate inclusion of three-nucleon interactions into ab initio nuclear structure calculations using a multi-reference formulation of normal ordering and Wick's t…
