Over the last decade, new developments in Similarity Renormalization Group techniques
and nuclear many-body methods have dramatically increased the capabilities of ab initio …

The nuclear shell model has perhaps been the most important conceptual and
computational paradigm for the understanding of the structure of atomic nuclei. While the …

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 …

The dominant decay mode of atomic nuclei is beta decay (β-decay), a process that changes
a neutron into a proton (and vice versa). This decay offers a window to physics beyond the …

Working with Hamiltonians from chiral effective field theory, we develop a novel framework
for describing arbitrary deformed medium-mass nuclei by combining the in-medium …

We calculate basis-space converged neutrinoless β β-decay nuclear matrix elements for the
lightest candidates: Ca 48, Ge 76, and Se 82. Starting from initial two-and three-nucleon …

Single-reference coupled-cluster theory is an accurate and affordable computational method
for the nuclear many-body problem. For open-shell nuclei, the reference state typically …

Background: Recent developments in ab initio nuclear theory demonstrate promising results
in medium-to heavy-mass nuclei. A particular challenge for many of the many-body …

In the shell-model framework, valence-space Hamiltonians connecting multiple major-
oscillator shells are of key interest for investigating the physics of neutron-rich nuclei, which …
