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 …

Reaction-rate modifications for chemical processes due to strong coupling between reactant
molecular vibrations and the cavity vacuum have been reported; however, no currently …

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

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 …

Here, we review the design of optical cavities, transient and modulated responses, and
theoretical models relevant to vibrational strong coupling (VSC). While planar Fabry–Perot …

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 …

Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …
