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

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 …

Abstract 2D monolayers supporting a wide variety of highly confined plasmons, phonon
polaritons, and exciton polaritons can be vertically stacked in van der Waals …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

Collective electronic modes or lattice vibrations usually prohibit propagation of
electromagnetic radiation through the bulk of common materials over a frequency range …

Hyperbolic polaritons exhibit large photonic density of states and can be collimated in
certain propagation directions. The majority of hyperbolic polaritons are sustained in man …

Excitons play a dominant role in the optoelectronic properties of atomically thin van der
Waals (vdW) semiconductors. These excitons are amenable to on-demand engineering with …

The interest in two-dimensional and layered materials continues to expand, driven by the
compelling properties of individual atomic layers that can be stacked and/or twisted into …

Low symmetry 2D materials with intrinsic in-plane anisotropic optical properties and high
tunability provide a promising platform to explore and manipulate light–matter interactions …

Natural hyperbolic materials (HMs) in two dimensions (2D) have an extraordinarily high
anisotropy and a hyperbolic dispersion relation. Some of them can even sustain hyperbolic …
