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 …

The study of open quantum systems–microscopic systems exhibiting quantum coherence
that are coupled to their environment–has become increasingly important in the past years …

Enhancing optical nonlinearities so that they become appreciable on the single photon level
and lead to nonclassical light fields has been a central objective in quantum optics for many …

Abstract The Jaynes‐Cummings model describes the coupling between photons and a
single two‐level atom in a simplified representation of light‐matter interactions. In circuit …

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 …

We demonstrate quantum bath engineering for a superconducting artificial atom coupled to
a microwave cavity. By tailoring the spectrum of microwave photon shot noise in the cavity …

We identify a new universality class in one-dimensional driven open quantum systems with
a dark state. Salient features are the persistence of both the microscopic nonequilibrium …

Dissipation generally leads to the decoherence of a quantum state. In contrast, numerous
recent proposals have illustrated that dissipation can also be tailored to stabilize many-body …

Controlling the spread of correlations in quantum many-body systems is a key challenge at
the heart of quantum science and technology. Correlations are usually destroyed by …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …
