The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

Metasurfaces are 2D artificial materials consisting of arrays of metamolecules, which are
exquisitely designed to manipulate light in terms of amplitude, phase, and polarization state …

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 …

Colloidal self-assembly refers to a solution-processed assembly of nanometer-/micrometer-
sized, well-dispersed particles into secondary structures, whose collective properties are …

<? pag\vskip-16pt?> Harnessing linear and angular momenta of light is one of the
cornerstones in modern optics and has found tremendous applications in optical circuits …

Bound states in the continuum (BICs) offer novel mechanisms to boost the quality factor (Q‐
factor) of resonances. Unfortunately, current studies on chiral BICs metasurfaces suffer from …

Optical tweezers and associated manipulation tools in the far field have had a major impact
on scientific and engineering research by offering precise manipulation of small objects …

Nanoscopic chiroptics studies the spin-dependent asymmetric light–matter interactions at
the nanoscale, where the asymmetry can stem from the intrinsic properties of materials …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

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 …
