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…
Can Ab Initio Theory Explain the Phenomenon of Parity Inversion in Be?
Angelo Calci, Petr Navrátil, Robert Roth +3
The weakly bound exotic Be nucleus, famous for its ground-state parity inversion and distinct n+ Be halo structure, is investigated from first principles using ch…
A nucleus-dependent valence-space approach to nuclear structure
S. R. Stroberg, A. Calci, H. Hergert +4
We present a nucleus-dependent valence-space approach for calculating ground and excited states of nuclei, which generalizes the shell-model in-medium similarity renormalization gr…
Induced Hyperon-Nucleon-Nucleon Interactions and the Hyperon Puzzle
Roland Wirth, Robert Roth
We present the first ab initio calculations for -shell hypernuclei including hyperon-nucleon-nucleon (YNN) contributions induced by a Similarity Renormalization Group transforma…
Hartree-Fock Many-Body Perturbation Theory for Nuclear Ground-States
Alexander Tichai, Joachim Langhammer, Sven Binder +1
We investigate the order-by-order convergence behavior of many-body perturbation theory (MBPT) as a simple and efficient tool to approximate the ground-state energy of closed-shell…
Sensitivities and correlations of nuclear structure observables emerging from chiral interactions
Angelo Calci, Robert Roth
Starting from a set of different two- and three-nucleon interactions from chiral effective field theory, we use the importance-truncated no-core shell model for ab initio calculati…
