Bayesian Analysis of EFT at Leading Order in a Modified Weinberg Power Counting Approach
Oliver Thim, Eleanor May, Andreas Ekström +1
We present a Bayesian analysis of renormalization-group invariant nucleon-nucleon interactions at leading order in chiral effective field theory (EFT) with momentum cutoffs in t…
Accurate bulk properties of nuclei from to from potentials with isobars
W. G. Jiang, A. Ekström, C. Forssén +3
We optimize -full nuclear interactions from chiral effective field theory. The low-energy constants of the contact potentials are constrained by two-body scattering phase shifts…
Finite-Size Effects in Heavy Halo Nuclei from Effective Field Theory
E. Ryberg, C. Forssén, D. R. Phillips +1
Halo/Cluster Effective Field Theory describes halo/cluster nuclei in an expansion in the small ratio of the size of the core(s) to the size of the system. Even in the point-particl…
Large-scale exact diagonalizations reveal low-momentum scales of nuclei
C. Forssén, B. D. Carlsson, H. T. Johansson +4
Ab initio methods aim to solve the nuclear many-body problem with controlled approximations. Virtually exact numerical solutions for realistic interactions can only be obtained for…
Uncertainty quantification for proton-proton fusion in chiral effective field theory
B. Acharya, B. D. Carlsson, A. Ekström +2
We compute the -factor of the proton-proton () fusion reaction using chiral effective field theory (EFT) up to next-to-next-to-leading order (NNLO) and perform a rigorous…
Accurate nuclear radii and binding energies from a chiral interaction
A. Ekström, G. R. Jansen, K. A. Wendt +7
With the goal of developing predictive ab-initio capability for light and medium-mass nuclei, two-nucleon and three-nucleon forces from chiral effective field theory are optimized…
Living on the edge of stability, the limits of the nuclear landscape
C. Forssen, G. Hagen, M. Hjorth-Jensen +2
A first-principles description of nuclear systems along the drip lines presents a substantial theoretical and computational challenge. In this paper, we discuss the nuclear theory…
The Similarity Renormalization Group for Three-Body Interactions in One Dimension
O. Åkerlund, E. J. Lindgren, J. Bergsten +5
We report on recent progress of the implementation of the similarity renormalization group (SRG) for three-body interactions in a one-dimensional, bosonic model system using the pl…
Charge radii and electromagnetic moments of Li and Be isotopes from the ab initio no-core shell model
C. Forssén, E. Caurier, P. Navrátil
Recently, charge radii and ground-state electromagnetic moments of Li and Be isotopes were measured precisely. We have performed large-scale ab initio no-core shell model calculati…
