Plasmonic phenomena in metals are commonly explored within the framework of classical
electrodynamics and semiclassical models for the interactions of light with free-electron …

The tremendous growth of the field of plasmonics in the past twenty years owes much to the
pre-existence of solid theoretical foundations. Rather than calling for the introduction of …

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 …

Acoustic graphene plasmons are highly confined electromagnetic modes carrying large
momentum and low loss in the mid-infrared and terahertz spectra. However, until now they …

We theoretically study the low-energy electromagnetic response of Bardeen-Cooper-
Schrieffer–type superconductors focusing on propagating collective modes that are …

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

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 …

An acoustic plasmon mode in a graphene-dielectric-metal structure has recently been
spotlighted as a superior platform for strong light-matter interaction. It originates from the …

A quantitative understanding of the electromagnetic response of materials is essential for the
precise engineering of maximal, versatile, and controllable light–matter interactions. Material …

Surface-response functions are one of the most promising routes for bridging the gap
between fully quantum-mechanical calculations and phenomenological models in quantum …
