Terahertz radiation has become an important diagnostic tool in the development of new
technologies. However, the diffraction limit prevents terahertz radiation (λ≈ 0.01–3 mm) …

In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

Plasmon polaritons are hybrid excitations of light and mobile electrons that can confine the
energy of long-wavelength radiation at the nanoscale. Plasmon polaritons may enable many …

As the first in a large family of 2D van der Waals (vdW) materials, graphene has attracted
enormous attention owing to its remarkable properties. The recent development of simple …

Polaritons, originating from the interactions between photons and material excitations, have
attracted attention because of their strong field compression and deeply subdiffractional …

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 …

Graphene is an atomically thin plasmonic medium that supports highly confined plasmon
polaritons, or nano-light, with very low loss. Electronic properties of graphene can be …

The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

Infrared and optical spectroscopy represents one of the most informative methods in
advanced materials research. As an important branch of modern optical techniques that has …

The ability to confine light into tiny spatial dimensions is important for applications such as
microscopy, sensing, and nanoscale lasers. Although plasmons offer an appealing avenue …
