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 …

In this review, we present the theoretical foundations and first-principles frameworks to
describe quantum matter within quantum electrodynamics (QED) in the low-energy regime …

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

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 …

Molecular polaritons are quasiparticles resulting from the hybridization between molecular
and photonic modes. These composite entities, bearing characteristics inherited from both …

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 …

Polaritons are a hybrid class of quasiparticles originating from the strong and resonant
coupling between light and matter excitations. Recent years have witnessed a surge of …

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 …

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 …
