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

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 …

It is possible to modify the chemical and physical properties of molecules, not only through
chemical modifications but also by coupling molecules strongly to light. More intriguingly …

Active optical elements with ever smaller footprint and lower energy consumption are central
to modern photonics. The drive for miniaturization, speed and efficiency, with the …

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 …

Bose–Einstein condensation describes the macroscopic occupation of a single-particle
mode: the condensate. This state can in principle be realized for any particles obeying Bose …

Research into strong light–matter interactions continues to fascinate, being spurred on by
unforeseen and often spectacular experimental observations. Properties that were …

Abstract Exciton–polariton Bose–Einstein condensation (EP BEC) is of crucial importance
for the development of coherent light sources and optical logic elements, as it creates a new …

Strong light-matter coupling provides the means to challenge the traditional rules of
chemistry. In particular, an energy inversion of singlet and triplet excited states would be …

Exciton-polaritons are quasiparticles with mixed photon and exciton character that
demonstrate rich quantum phenomena, novel optoelectronic devices and the potential to …
