A particular strength of ultracold quantum gases is the range of versatile detection methods
that are available. As they are based on atom–light interactions, the whole quantum optics …

This review describes the field of Bose polarons, arising when mobile impurities are
immersed into a bosonic quantum gas. The latter can be realized by a Bose-Einstein …

We investigate the structure of many-body wave functions of 1D quantum circuits with local
measurements employing the participation entropies. The leading term in system size …

Atoms with a highly excited electron, called Rydberg atoms, can form unusual types of
molecular bonds,,–. The bonds differ from the well-known ionic and covalent bonds, not only …

Vibrational dynamics in conventional molecules usually takes place on a timescale of
picoseconds or shorter. A striking exception are ultralong-range Rydberg molecules, for …

Imaging is central to gaining microscopic insight into physical systems, and new microscopy
methods have always led to the discovery of new phenomena and a deeper understanding …

Quantum systems evolving unitarily and subject to quantum measurements exhibit various
types of non-equilibrium phase transitions, arising from the competition between unitary …

The presence of strong interactions in a many-body quantum system can lead to a variety of
exotic effects. Here we show that even in a comparatively simple setup consisting of a …

We explore the interaction between two trapped ions mediated by a surrounding quantum
degenerate Bose or Fermi gas. Using perturbation theory valid for weak atom-ion …

Cavity quantum electrodynamics offers the possibility of observing and controlling the
motion of a few or individual atoms, enabling the realization of various quantum …
