When molecules are coupled to an optical cavity, new light–matter hybrid states, so-called
polaritons, are formed due to quantum light–matter interactions. With the experimental …

The interaction between molecular electronic transitions and electromagnetic fields can be
enlarged to the point where distinct hybrid light–matter states, polaritons, emerge. The …

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 …

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 …

Molecular polaritons result from light-matter coupling between optical resonances and
molecular electronic or vibrational transitions. When the coupling is strong enough, new …

Polaritonic chemistry exploits strong light–matter coupling between molecules and confined
electromagnetic field modes to enable new chemical reactivities. In systems displaying this …

Abstract Ultraviolet (UV, λ< 400 nm) light is essential for various photochemical reactions,
but its intensity in the solar spectrum is very low, and light sources that artificially generate …

Discoveries in quantum materials, which are characterized by the strongly quantum-
mechanical nature of electrons and atoms, have revealed exotic properties that arise from …

Exciton-polaritons are hybrid states formed when molecular excitons are strongly coupled to
photons trapped in an optical cavity. These systems exhibit many interesting, but not fully …
