Surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS)
have opened a variety of exciting research fields. However, although a vast number of …

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

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

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 …

Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

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

Here, we present a fundamental study on how the ground-state chemical reactivity of a
single molecule can be modified in a QED scenario, ie, when it is placed inside a nanoscale …

Tip-enhanced Raman spectroscopy (TERS) is a versatile tool for chemical analysis at the
nanoscale. In earlier TERS experiments, Raman modes with components parallel to the tip …

Strong coupling between plasmons in metal nanoparticles and single excitons in molecules
or semiconductor nanomaterials has recently attracted considerable experimental effort for …

Surface-enhanced Raman spectroscopy (SERS) has evolved significantly over fifty years
into a powerful analytical technique. This review aims to achieve five main goals.(1) …
