In this review recent investigations are summarized of many-body quantum systems with
long-range interactions, which are currently realized in Rydberg atom arrays, dipolar …

We review the recent developments and the current status in the field of quantum-gas cavity
QED. Since the first experimental demonstration of atomic self-ordering in a system …

The control over quantum states in atomic systems has led to the most precise optical atomic
clocks so far,–. Their sensitivity is bounded at present by the standard quantum limit, a …

Quantum simulators are a promising technology on the spectrum of quantum devices from
specialized quantum experiments to universal quantum computers. These quantum devices …

Interactions between atoms and light in optical cavities provide a means of investigating
collective (many-body) quantum physics in controlled environments. Such ensembles of …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

The light-matter interaction can be utilized to qualitatively alter physical properties of
materials. Recent theoretical and experimental studies have explored this possibility of …

We report direct observations of photon-mediated spin-exchange interactions in an atomic
ensemble. Interactions extending over a distance of 500 μ m are generated within a cloud of …

The Dicke model—a paradigmatic example of superradiance in quantum optics—describes
an ensemble of atoms which are collectively coupled to a leaky cavity mode. As a result of …

Quantum emitters coupled to optical resonators are quintessential systems for exploring
fundamental phenomena in cavity quantum electrodynamics (cQED) and are commonly …
