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

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 …

Subjecting a physical system to extreme conditions is one of the means often used to obtain
a better understanding and deeper insight into its organization and structure. In the case of …

Effective field theory allows for a systematic and model-independent derivation of the forces
between nucleons in harmony with the symmetries of quantum chromodynamics. The …

We link the structure of nuclei around Sn 100, the heaviest doubly magic nucleus with equal
neutron and proton numbers (N= Z= 50), to nucleon-nucleon (NN) and three-nucleon (NNN) …

It is often assumed that few-and many-body systems can be accurately described by
considering only pairwise two-body interactions of the constituents. We illustrate that three …

We present nuclear matter calculations based on low-momentum interactions derived from
chiral effective field theory potentials. The current calculations use an improved treatment of …

We present an overview of low-momentum two-nucleon and many-body interactions and
their use in calculations of nuclei and infinite matter. The softening of phenomenological and …

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 …

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 …
