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…
Charge, neutron, and weak size of the atomic nucleus
G. Hagen, A. Ekström, C. Forssén +14
What is the size of the atomic nucleus? This deceivably simple question is difficult to answer. While the electric charge distributions in atomic nuclei were measured accurately al…
Uncertainty analysis and order-by-order optimization of chiral nuclear interactions
B. D. Carlsson, A. Ekström, C. Forssén +6
Chiral effective field theory (chiEFT) provides a systematic approach to describe low-energy nuclear forces. Moreover, chiEFT is able to provide well-founded estimates of statistic…
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…
Uncertainty Quantification of the Pion-Nucleon Low-Energy Coupling Constants up to Fourth Order in Chiral Perturbation Theory
K. A. Wendt, B. D. Carlsson, A. Ekström
We extract the statistical uncertainties for the pion-nucleon () low energy constants (LECs) up to fourth order in the chiral expansion of the nuclear effect…
Statistical uncertainties of a chiral interaction at next-to-next-to leading order
A. Ekström, B. D. Carlsson, K. A. Wendt +4
We have quantified the statistical uncertainties of the low-energy coupling-constants (LECs) of an optimized nucleon-nucleon (NN) interaction from chiral effective field theory ($χ…
Effects of three-nucleon forces and two-body currents on Gamow-Teller strengths
A. Ekström, G. R. Jansen, K. A. Wendt +5
We optimize chiral interactions at next-to-next-to leading order to observables in two- and three-nucleon systems, and compute Gamow-Teller transitions in carbon-14, oxygen-22 and…
