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 …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

Abstract 0D perovskites have gained much attention in recent years due to their fascinating
properties derived from their peculiar structure with isolated metal halide octahedra or metal …

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 …

Lead-halide perovskites are generally excellent light emitters and can have larger exciton
binding energies than thermal energy at room temperature, exhibiting great promise for …

The power of chemistry to prepare new molecules and materials has driven the quest for
new approaches to solve problems having global societal impact, such as in renewable …

Self‐trapped excitons (STEs) have recently attracted tremendous interest due to their
broadband emission, high photoluminescence quantum yield, and self‐absorption‐free …

Molecular polaritons result from light-matter coupling between optical resonances and
