Family of Chiral Two- plus Three-Nucleon Interactions for Accurate Nuclear Structure Studies
Thomas Hüther, Klaus Vobig, Kai Hebeler +2
We present a family of nucleon-nucleon (NN) plus three-nucleon (3N) interactions up to N3LO in the chiral expansion that provides an accurate ab initio description of ground-state…
Natural orbitals for ab initio no-core shell model calculations
Alexander Tichai, Julius Müller, Klaus Vobig +1
We explore the impact of optimizations of the single-particle basis on the convergence behavior and robustness of ab initio no-core shell model calculations. Our focus is on novel…
Few- and many-nucleon systems with semilocal coordinate-space regularized chiral two- and three-body forces
E. Epelbaum, J. Golak, K. Hebeler +12
We present a complete calculation of nucleon-deuteron scattering as well as ground and low-lying excited states of light nuclei in the mass range A=3-16 up through next-to-next-to-…
Few- and many-nucleon systems with semilocal coordinate-space regularized chiral nucleon-nucleon forces
S. Binder, A. Calci, E. Epelbaum +15
We employ a variety of ab initio methods including Faddeev-Yakubovsky equations, No-Core Configuration Interaction Approach, Coupled-Cluster Theory and In-Medium Similarity Renorma…
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…
Ab Initio Calculations of Medium-Mass Nuclei with Normal-Ordered Chiral NN+3N Interactions
Robert Roth, Sven Binder, Klaus Vobig +3
We study the use of truncated normal-ordered three-nucleon interactions in ab initio nuclear structure calculations starting from chiral two- plus three-nucleon Hamiltonians evolve…
