Effective field theory in the harmonic oscillator basis
S. Binder, A. Ekström, G. Hagen +2
We develop interactions from chiral effective field theory (EFT) that are tailored to the harmonic oscillator basis. As a consequence, ultraviolet convergence with respect to the m…
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…
Infrared length scale and extrapolations for the no-core shell model
K. A. Wendt, C. Forssén, T. Papenbrock +1
We precisely determine the infrared (IR) length scale of the no-core shell model (NCSM). In the NCSM, the -body Hilbert space is truncated by the total energy, and the IR length…
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…
