In spite of missing dynamical correlations, the projected generator coordinate method (PGCM) was recently shown to be a suitable method to tackle the low-lying spectroscopy of complex nuclei. Still, describing absolute binding energies and reaching high accuracy eventually requires the inclusion of dynamical correlations on top of the PGCM. In this context, the present work discusses the first realistic results of a novel multi-reference perturbation theory (PGCM-PT) that can do so within a…

Angular-momentum projection in coupled-cluster theory: structure of $^{34}$Mg
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 breaks rotational
Symmetry restoration methods
Symmetry techniques based on group theory play a prominent role in the analysis of nuclear phenomena, and in particular in the understanding of observed regular patterns in nuclear spectra and
Neutrinoless Double-Beta Decay: A Roadmap for Matching Theory to Experiment
The observation of neutrino oscillations and hence non-zero neutrino masses provided a milestone in the search for physics beyond the Standard Model. But even though we now know that neutrinos are
Least-square approach for singular value decompositions of scattering problems
TLDR
The feasibility of the least-square approach is verified by solving the Lippmann-Schwinger equation in factorized form and the resulting low-rank approximations of the T matrix are found to fully capture scattering observables.
On the off-diagonal Wick's theorem and Onishi formula
The projected generator coordinate method based on the configuration mixing of non-orthogonal Bogoliubov product states, along with more advanced methods based on it, require the computation of

In-medium similarity renormalization group for closed and open-shell nuclei
We present a pedagogical introduction to the In-Medium Similarity Renormalization Group (IM-SRG) framework for ab initio calculations of nuclei. The IM-SRG performs continuous unitary transformations
In-medium k-body reduction of n-body operators
The computational cost of ab initio nuclear structure calculations is rendered particularly acute by the presence of (at least) three-nucleon interactions. This feature becomes especially critical
Ab initio Bogoliubov coupled cluster theory for open-shell nuclei
Background: Ab initio many-body methods have been developed over the past 10 yr to address closed-shell nuclei up to mass A≈130 on the basis of realistic two- and three-nucleon interactions. A
In-Medium No-Core Shell Model for Ab Initio Nuclear Structure Calculations
In this work, we merge two successful ab initio nuclear-structure methods, the no-core shell model (NCSM) and the multi-reference in-medium similarity renormalization group (IM-SRG), to define a
ADG: automated generation and evaluation of many-body diagrams
The goal of the present paper is twofold. First, a novel expansion many-body method applicable to superfluid open-shell nuclei, the so-called Bogoliubov in-medium similarity renormalization group
Normal-ordered k-body approximation in particle-number-breaking theories
The reach of ab initio many-body theories is rapidly extending over the nuclear chart. However, dealing fully with three-nucleon, possibly four-nucleon, interactions makes the solving of the A-body
