BACKGROUND One of the most important phenomena in cavity quantum electrodynamics
(cQED) is the so-called strong coupling regime, which appears when the interaction …

This Review focuses on the integration of plasmonic and dielectric metasurfaces with
emissive or stimuli-responsive materials for manipulating light–matter interactions at the …

Over the past decade, the possibility of manipulating chemistry and material properties using
hybrid light–matter states has stimulated considerable interest. Hybrid light–matter states …

The prospect of controlling the electronic properties of materials via the vacuum fields of
cavity electromagnetic resonators is emerging as one of the frontiers of condensed matter …

Recent experiments have demonstrated that light and matter can mix together to an extreme
degree, and previously uncharted regimes of light-matter interactions are currently being …

Hybrid excitations, called polaritons, emerge in systems with strong light–matter coupling.
Usually, they dominate the linear and nonlinear optical properties with applications in …

Light–Matter strong coupling in the vacuum limit has been shown, over the past decade, to
enhance material properties. Oxide nanoparticles are known to exhibit weak ferromagnetism …

It is well known that symmetry plays a key role in chemical reactivity. Here we explore its role
in vibrational strong coupling (VSC) for a charge‐transfer (CT) complexation reaction. By …

This article reviews theoretical methods developed in the last decade to understand cavity
quantum electrodynamics in the ultrastrong‐coupling regime, where the strength of the light …

We study the quantum Hall effect in a two-dimensional homogeneous electron gas coupled
to a quantum cavity field. As initially pointed out by Kohn, Galilean invariance for a …
