Ultrastrong coupling between light and matter has, in the past decade, transitioned from a
theoretical idea to an experimental reality. It is a new regime of quantum light–matter …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

It is possible to modify the chemical and physical properties of molecules, not only through
chemical modifications but also by coupling molecules strongly to light. More intriguingly …

The demonstration of strong and ultrastrong coupling regimes of cavity QED with polyatomic
molecules has opened new routes to control chemical dynamics at the nanoscale. We show …

This is a tutorial-style introduction to the field of molecular polaritons. We describe the basic
physical principles and consequences of strong light–matter coupling common to molecular …

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

We revisit the derivation of Rabi-and Dicke-type models, which are commonly used for the
study of quantum light-matter interactions in cavity and circuit QED. We demonstrate that the …

We study a generic cavity-QED system where a set of (artificial) two-level dipoles is coupled
to the electric field of a single-mode LC resonator. This setup is used to derive a minimal …

Angle-independent narrowband emission is required for many optoelectronic devices,
ranging from high-definition displays to sensors. However, emerging materials for …

Exciton-polaritons are bosonic quasiparticles that arise from the normal mode splitting of
photons in a microcavity and excitons in a semiconductor material. One of the most …
