several complementary ab initio many-body techniques applicable to light and medium …

Perturbative and non-perturbative expansion methods already constitute a tool of choice to
perform ab initio calculations over a significant part of the nuclear chart. In this context, the …

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 …

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 …

First principles calculations of atomic nuclei based on microscopic nuclear forces derived
from chiral effective field theory (EFT) have blossomed in the past years. A key element of …

The past three decades have witnessed the emergence of exotic structures and dynamics in
weakly bound unstable nuclei located in the rapidly expanding nuclear chart. Examples …

Nuclear weak decays provide important probes to fundamental symmetries in nature. A
precise description of these processes in atomic nuclei requires comprehensive knowledge …
