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

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 …

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 …

Recent experiments suggest that ground state chemical reactivity can be modified when
placing molecular systems inside infrared cavities where molecular vibrations are strongly …

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 …

Recent experiments demonstrate the control of chemical reactivities by coupling molecules
inside an optical microcavity. In contrast, transition state theory predicts no change of the …

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

Strong coupling between molecules and confined light modes of optical cavities to form
polaritons can alter photochemistry, but the origin of this effect remains largely unknown …
