Hexagonal boron nitride (h‐BN) has emerged as a strong candidate for two‐dimensional
(2D) material owing to its exciting optoelectrical properties combined with mechanical …

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 …

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 …

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 …

Metasurfaces, two-dimensional equivalents of metamaterials, are engineered surfaces
consisting of deep subwavelength features that have full control of the electromagnetic …

Two-dimensional van der Waals materials have emerged as promising platforms for solid-
state quantum information processing devices with unusual potential for heterogeneous …

Conventional optical components are limited to size scales much larger than the wavelength
of light, as changes to the amplitude, phase and polarization of the electromagnetic fields …

Element isotopes are characterized by distinct atomic masses and nuclear spins, which can
significantly influence material properties. Notably, however, isotopes in natural materials …

Hexagonal boron nitride (h-BN) is a natural hyperbolic material, in which the dielectric
constants are the same in the basal plane (ε t≡ ε x= ε y) but have opposite signs (ε t ε z< 0) …
