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 …

Phonon polaritons—light coupled to lattice vibrations—in polar van der Waals crystals are
promising candidates for controlling the flow of energy on the nanoscale due to their strong …

The ability to control the interaction of light and matter at the nanoscale is at the heart of the
field of nanophotonics. This subdiffractional confinement of light can be achieved through …

Phonon polaritons localized in polar nanoresonators and superlattices are being actively
investigated as promising platforms for midinfrared nanophotonics. Here we show that the …

We present a generalized formalism to describe the optical energy flow and spatially
resolved absorption in arbitrarily anisotropic layered structures. The algorithm is capable of …

Polar dielectric nanoresonators can support hybrid photon-phonon modes termed surface
phonon polaritons with length scales below the diffraction limit. In the deep subwavelength …

We investigate the frontier between classical and quantum plasmonics in highly doped
semiconductor layers. The choice of a semiconductor platform instead of metals for our study …

Polar dielectrics are a promising platform for midinfrared nanophotonics, allowing for
nanoscale electromagnetic energy confinement in oscillations of the crystal lattice. We …

Graphene plasmons provide a compelling avenue toward chip-scale dynamic tuning of
infrared light. Dynamic tunability emerges through controlled alterations in the optical …

There have been many great advances in the generation and manipulation of optics in the
visible and near infrared (IR) range over the past decade. This is largely due to plasmonic …
