Journal ArticleDOI
Accurate nuclear radii and binding energies from a chiral interaction
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
Coupled-cluster calculations of nucleonic matter
Gaute Hagen,Gaute Hagen,Thomas Papenbrock,Thomas Papenbrock,Andreas Ekström,Andreas Ekström,K. A. Wendt,K. A. Wendt,G. Baardsen,Stefano Gandolfi,Morten Hjorth-Jensen,Morten Hjorth-Jensen,Charles Horowitz +12 more
TL;DR: In this paper, the authors presented coupled-cluster calculations of infinite nucleonic matter using modern interactions from chiral effective field theory (EFT), and the role of three-nucleon forces (3NFs) in nuclear matter calculations with chiral interactions.
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
Infrared length scale and extrapolations for the no-core shell model
K. A. Wendt,K. A. Wendt,Christian Forssén,Christian Forssén,Christian Forssén,Thomas Papenbrock,Thomas Papenbrock,Daniel Sääf +7 more
TL;DR: In this paper, the authors determined the IR length scale of the no-core shell model by equating the intrinsic kinetic energy of a nucleon in the NCSM space to that of A nucleons in a 3(A - 1)-dimensional hyper-radial well with a Dirichlet boundary condition for the hyper radius.
