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

The coherent exchange of energy between materials and optical fields leads to strong light–
matter interactions and so-called polaritonic states with intriguing properties, halfway …

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 …

Chemical manifestations of strong light–matter coupling have recently been a subject of
intense experimental and theoretical studies. Here we review the present status of this field …

Thin layers of in-plane anisotropic materials can support ultraconfined polaritons, whose
wavelengths depend on the propagation direction. Such polaritons hold potential for the …

Experiments at the interface of quantum optics and chemistry have revealed that strong
coupling between light and matter can substantially modify the chemical and physical …

Polaritonic chemistry is emerging as a powerful approach to modifying the properties and
reactivity of molecules and materials. However, probing how the electronics and dynamics of …

The topological structure associated with the branch point singularity around an exceptional
point (EP) can provide tools for controlling the propagation of light. Through use of graphene …

Light‐molecule strong coupling has emerged within the last decade as a new method to
control chemical reactions. A few years ago it was discovered that chemical reactivity could …

We present a combined analytical and numerical study for coherent terahertz control of a
single molecular polariton, formed by strongly coupling two rotational states of a molecule …
