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

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

J‐aggregates are of significant interest for organic materials conceived by supramolecular
approaches. Their discovery in the 1930s represents one of the most important milestones in …

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 …

Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

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 …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

Just as atoms exchange electrons to form molecular orbitals, an electromagnetic field can
interact with a quantum system by the exchange of photons. When this interaction is strong …

The Jaynes–Cummings Model (JCM) has recently been receiving increased attention as
one of the simplest, yet intricately nonlinear, models of quantum physics. Emphasising the …

The demonstration of strong and ultrastrong coupling regimes of cavity QED with polyatomic
molecules has opened new routes to control chemical dynamics at the nanoscale. We show …
