Journal ArticleDOI

Andreas Ekström,Andreas Ekström,Gustav R. Jansen,Gustav R. Jansen,K. A. Wendt,K. A. Wendt,Gaute Hagen,Gaute Hagen,Thomas Papenbrock,Thomas Papenbrock,B. D. Carlsson,Christian Forssén,Christian Forssén,Christian Forssén,Morten Hjorth-Jensen,Morten Hjorth-Jensen,Petr Navrátil,Witold Nazarewicz,Witold Nazarewicz,Witold Nazarewicz +19 more
TL;DR: In this paper, two-nucleon and three-Nucleon forces from chiral effective field theory are optimized simultaneously to low-energy nucleon-Nuclear scattering data, as well as binding energies and radii of few nucleon systems and selected isotopes of carbon and oxygen.
Journal ArticleDOI

TL;DR: In this article, an ab initio calculation of the neutron distribution of the Neutron-rich nucleus Ca-48 is presented, and it is shown that the difference between the radii of the neutrons and proton distributions is significantly smaller than previously thought.
Journal ArticleDOI
Uncertainty Analysis and Order-by-Order Optimization of Chiral Nuclear Interactions
B. D. Carlsson,Andreas Ekström,Andreas Ekström,Christian Forssén,Christian Forssén,Christian Forssén,D. Fahlin Strömberg,Gustav R. Jansen,Gustav R. Jansen,Oskar Lilja,M. Lindby,B. A. Mattsson,K. A. Wendt,K. A. Wendt +13 more
TL;DR: It is found that a simultaneous fit to different sets of data is critical to identify the optimal set of LECs, capture all relevant correlations, reduce the statistical uncertainty, and attain order-by-order convergence in chi EFT.
Journal ArticleDOI
Effects of three-nucleon forces and two-body currents on Gamow-Teller strengths.
Andreas Ekström,Gustav R. Jansen,Gustav R. Jansen,K. A. Wendt,K. A. Wendt,Gaute Hagen,Gaute Hagen,Thomas Papenbrock,Thomas Papenbrock,Sonia Bacca,Sonia Bacca,B. D. Carlsson,Doron Gazit +12 more
TL;DR: It is shown that chiral interactions at next-to-next-to leading order to observables in two- and three-nucleon systems and Gamow-Teller transitions in 14C and (22,24)O using consistent two-body currents reduce the Ikeda sum rule.
Journal ArticleDOI
Large-scale exact diagonalizations reveal low-momentum scales of nuclei
Christian Forssén,B. D. Carlsson,Håkan T Johansson,Daniel Sääf,Aaina Bansal,Gaute Hagen,Thomas Papenbrock +6 more
TL;DR: In this article, the authors extend the reach of exact diagonalization methods to handle model spaces with dimension exceeding 10(10) on a single compute node, which allows them to perform no-core shell model (NCSM) calculations for Li-6 in model spaces up to N-max = 22 and to reveal the He-4+d halo structure of this nucleus.
