The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be
accurately calculated if experiments are to reach their full potential. Theorists have been …

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 atomic nucleus is a quantum many-body system whose constituent nucleons (protons
and neutrons) are subject to complex nucleon-nucleon interactions that include spin-and …

Motivated by limitations of the Bloch–Horowitz–Brandow perturbative approach to nuclear
structure we have developed the non-perturbative ab initio no core shell model (NCSM) …

In the past decade, coupled-cluster theory has seen a renaissance in nuclear physics, with
computations of neutron-rich and medium-mass nuclei. The method is efficient for nuclei …

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 …

We present a comprehensive review of the In-Medium Similarity Renormalization Group (IM-
SRG), a novel ab initio method for nuclei. The IM-SRG employs a continuous unitary …

We present an overview of recent results and developments of the no-core shell model
(NCSM), an ab initio approach to the nuclear many-body problem for light nuclei. In this …

Recent advances in nuclear structure theory have significantly enlarged the accessible part
of the nuclear landscape via ab initio many-body calculations. These developments open …

We present a nucleus-dependent valence-space approach for calculating ground and
excited states of nuclei, which generalizes the shell-model in-medium similarity …
