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

Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

Ambitions to reach atomic resolution with light have been a major force in sha** nano-
optics, whereby a central challenge is achieving highly localized optical fields. A promising …

The excitation of surface plasmons (SPs)—collective oscillation of conduction-band
electrons in nanostructures—can afford photon, electron and heat energy redistribution over …

Quantum mechanical interactions between electromagnetic radiation and matter underlie a
broad spectrum of optical phenomena. Strong light-matter interactions result in the well …

Molecular junctions are building blocks for constructing future nanoelectronic devices that
enable the investigation of a broad range of electronic transport properties within nanoscale …

Enhanced light-matter interactions are the basis of surface-enhanced infrared absorption
(SEIRA) spectroscopy, and conventionally rely on plasmonic materials and their capability to …

Phonon polaritons in van der Waals materials can strongly enhance light–matter interactions
at mid-infrared frequencies, owing to their extreme field confinement and long lifetimes …

The structure determination of surface species has long been a challenge because of their
rich chemical heterogeneities. Modern tip-based microscopic techniques can resolve …

The large losses of plasmonic nanocavities, orders of magnitude beyond those of photonic
dielectric cavities, places them, perhaps surprisingly, as exceptional enhancers of single …
