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 …

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

Polaritons, resulting from the hybridization of light with polarization charges formed at the
boundaries between media with positive and negative dielectric response functions, can …

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 …

Emerging van der Waals materials exhibit a wide range of optical and electronic properties,
making them attractive for nanophotonic devices. Due to the nature of van der Waals …

Polaritons—hybrid light–matter excitations—enable nanoscale control of light. Particularly
large polariton field confinement and long lifetimes can be found in graphene and materials …

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

Polaritonic modes in low-dimensional materials enable strong light–matter interactions and
the manipulation of light on nanometer length scales. Very recently, a new class of …

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 …

Negative refraction provides a platform to manipulate mid-infrared and terahertz radiation for
molecular sensing and thermal emission applications. However, its implementation based …
