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

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 …

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

Molecular polaritons are hybrid light-matter states that emerge when a molecular transition
strongly interacts with photons in a resonator. At optical frequencies, this interaction unlocks …

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

Vibrational strong coupling (VSC) between molecular vibrations and microcavity photons
yields a few polaritons (light-matter modes) and many dark modes (with negligible photonic …

While there have been numerous reports of long‐range polariton transport at room‐
temperature in organic cavities, the spatiotemporal evolution of the propagation is scarcely …

The strong coherent coupling of quantum emitters to vacuum fluctuations of the light field
offers opportunities for manipulating the optical and transport properties of nanomaterials …

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