This is a review of state-of-the-art theory and experiment of the motion of cold and ultracold
atoms coupled to the radiation field within a high-finesse optical resonator in the dispersive …

Distributed quantum networks will allow users to perform tasks and to interact in ways which
are not possible with present-day technology. Their implementation is a key challenge for …

The counter-intuitive aspects of quantum physics have been for long illustrated by thought
experiments, from Einstein's photon box to Schrödinger's cat. These experiments have now …

Policies to reduce emissions from deforestation would benefit from clearly derived, spatially
explicit, statistically bounded estimates of carbon emissions. Existing efforts derive carbon …

This paper reviews the work on cavity quantum electrodynamics of free atoms. In recent
years, cavity experiments have also been conducted on a variety of solid-state systems …

We present an ideal realization of the Tavis-Cummings model in the absence of atom
number and coupling fluctuations by embedding a discrete number of fully controllable …

Long-range interactions in quantum gases are predicted to give rise to an excitation
spectrum of roton character, similar to that observed in superfluid helium. We investigated …

A density wave (DW) is a fundamental type of long-range order in quantum matter tied to self-
organization into a crystalline structure. The interplay of DW order with superfluidity can lead …

Strong interactions can amplify quantum effects such that they become important on
macroscopic scales. Controlling these coherently on a single-particle level is essential for …

Long-lived quasi-stationary states (QSSs) are a signature characteristic of long-range
interacting systems both in the classical and in the quantum realms. Often, they emerge after …
