Unexpected Rise in Nuclear Collectivity from Short-Range Physics
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +4
We discover a surprising relation between the collective motion of nucleons within atomic nuclei, traditionally understood to be driven by long-range correlations, and short-range…
Quantifying the breakdown scale of pionless effective field theory
Andreas Ekström, Lucas Platter
We use Bayesian statistics to infer the breakdown scale of pionless effective field theory in its standard power counting and with renormalization of observables carried out using…
Uncertainty Quantification of Collective Nuclear Observables From the Chiral Potential Parametrization
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +4
We perform an uncertainty estimate of quadrupole moments and B(E2) transition rates that inform nuclear collectivity. In particular, we study the low-lying states of 6Li and 12C us…
Perturbative computations of neutron-proton scattering observables using renormalization-group invariant EFT up to NLO
Oliver Thim, Andreas Ekström, Christian Forssén
We predict neutron-proton scattering cross-sections and polarization observables up to next-to-next-to-next-to leading order in a renormalization-group invariant description of the…
Eigenvector Continuation and Projection-Based Emulators
Thomas Duguet, Andreas Ekström, Richard J. Furnstahl +2
Eigenvector continuation is a computational method for parametric eigenvalue problems that uses subspace projection with a basis derived from eigenvector snapshots from different p…
Inference of the low-energy constants in -full chiral effective field theory including a correlated truncation error
Isak Svensson, Andreas Ekström, Christian Forssén
We sample the posterior probability distributions of the low-energy constants (LECs) in -full chiral effective field theory (EFT) up to third order. We use eigenvector contin…
