Recent experimental developments in diverse areas—ranging from cold atomic gases to
light-driven semiconductors to microcavity arrays—move systems into the focus which are …

Photonic synthetic materials provide an opportunity to explore the role of microscopic
quantum phenomena in determining macroscopic material properties. There are, however …

The Dicke model describes the coupling between a quantized cavity field and a large
ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can …

In this article we provide a review of geometrical methods employed in the analysis of
quantum phase transitions and non-equilibrium dissipative phase transitions. After a …

Insights into complex phenomena in quantum matter can be gained from simulation
experiments with ultracold atoms, especially in cases where theoretical characterization is …

The physics of one-dimensional interacting bosonic systems is reviewed. Beginning with
results from exactly solvable models and computational approaches, the concept of bosonic …

The Dicke model with a weak dissipation channel is realized by coupling a Bose–Einstein
condensate to an optical cavity with ultranarrow bandwidth. We explore the dynamical …

We review the depinning and nonequilibrium phases of collectively interacting particle
systems driven over random or periodic substrates. This type of system is relevant to vortices …

We explore the nature of the Bose condensation transition in driven open quantum systems,
such as exciton-polariton condensates. Using a functional renormalization group approach …

The enormous experimental progress in atomic, molecular, and optical (AMO) physics
during the last decades allows us nowadays to isolate single, a few or even many-body …
