How chiral forces shape neutron-rich Ne and Mg nuclei
Andreas Ekström, Christian Forssén, G. Hagen +3
We compute the structure of the exotic even nuclei Ne and Mg using interactions from chiral effective field theory (EFT). Our results for the ground-state rotat…
Ab Initio Symmetry-Adapted Emulator for Studying Emergent Collectivity and Clustering in Nuclei
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +1
We discuss emulators from the ab initio symmetry-adapted no-core shell-model framework for studying the formation of alpha clustering and collective properties without effective ch…
Ab initio predictions link the neutron skin of Pb to nuclear forces
Baishan Hu, Weiguang Jiang, Takayuki Miyagi +8
Heavy atomic nuclei have an excess of neutrons over protons, which leads to the formation of a neutron skin whose thickness is sensitive to details of the nuclear force. This links…
Fast & rigorous predictions for nuclei with Bayesian posterior sampling
T. Djärv, A. Ekström, C. Forssén +1
We make ab initio predictions for the A = 6 nuclear level scheme based on two- and three-nucleon interactions up to next-to-next-to-leading order in chiral effective field theory (…
Ab initio models of atomic nuclei: challenges and new ideas
Andreas Ekström
This review presents some of the challenges in constructing models of atomic nuclei starting from theoretical descriptions of the strong interaction between nucleons. The focus is…
Improved many-body expansions from eigenvector continuation
Pepijn Demol, Thomas Duguet, Andreas Ekström +7
Quantum many-body theory has witnessed tremendous progress in various fields, ranging from atomic and solid-state physics to quantum chemistry and nuclear structure. Due to the inh…
