Polaritons are hybrid excitations of matter and photons. In recent years, polaritons in van der
Waals nanomaterials—known as van der Waals polaritons—have shown great promise to …

Two-dimensional (2D) materials including graphene, transition metal dichalcogenides, black
phosphorus, MXenes, and semimetals have attracted extensive and widespread interest …

Hexagonal boron nitride (h‐BN), an insulating 2D layered material, has recently attracted
tremendous interest motivated by the extraordinary properties it shows across the fields of …

For more than seven decades, hexagonal boron nitride (hBN) has been employed as an
inert, thermally stable engineering ceramic; since 2010, it has also been used as the optimal …

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 …

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

In recent years, enhanced light–matter interactions through a plethora of dipole-type
polaritonic excitations have been observed in two-dimensional (2D) layered materials. In …

BACKGROUND Light trapped at the nanoscale, deep below the optical wavelength, exhibits
an increase in the associated electric field strength, which results in enhanced light-matter …

Moiré engineering is being intensively investigated as a method to tune the electronic,
magnetic and optical properties of twisted van der Waals materials. Advances in moiré …

The spectrum of two-dimensional (2D) and layered materials 'beyond graphene'offers a
remarkable platform to study new phenomena in condensed matter physics. Among these …
