Few-body physics has played a prominent role in atomic, molecular and nuclear physics
since the early days of quantum mechanics. It is now possible—thanks to tremendous …

Quantum phenomena of many-particle systems are fascinating in their complexity and are
consequently not fully understood and largely untapped in terms of practical applications …

Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

We consider a trapped atomic ensemble of interacting bosons in the presence of a single
trapped ion in a quasi-one-dimensional geometry. Our study is carried out by means of the …

Systems consisting of few interacting fermions are the building blocks of matter, with atoms
and nuclei being the most prominent examples. We have created a few-body quantum …

Recent advances in controlling interatomic interactions, coupled with new techniques for
producing and interrogating exotic regimes in ultracold quantum gases, have resulted in the …

The recent advances in single atom detection and manipulation in experiments with
ultracold quantum gases are reviewed. The discussion starts with the basic principles of …

We investigate the transition of a quasi-one-dimensional few-boson system from a weakly
correlated to a fragmented and finally a fermionized ground state. Our numerically exact …

The nature of strongly interacting Fermi gases and magnetism is one of the most important
and studied topics in condensed-matter physics. Still, there are many open questions. A …
