Nanophotonics offers opportunities for engineering and exploiting the quantum properties of
light by integrating quantum emitters into nanostructures, and offering reliable paths to …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Exploiting the interplay between gain, loss and the coupling strength between different
optical components creates a variety of new opportunities in photonics to generate, control …

Plasmon-mediated chemical reactions (PMCRs) are processes that make use of
nanostructure-based surface plasmons as mediators to redistribute and convert photon …

The interaction of light and matter at the single-photon level is of central importance in
various fields of physics, including, eg, condensed matter physics, astronomy, quantum …

Color centers in hexagonal boron nitride (hBN) have recently emerged as promising
candidates for a new wave of quantum applications. Thanks to hBN's high stability and two …

Ultrastrong coupling between light and matter has, in the past decade, transitioned from a
theoretical idea to an experimental reality. It is a new regime of quantum light–matter …

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 …

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 …

The vast development of nanofabrication has spurred recent progress for the manipulation
of light down to a region much smaller than the wavelength. Metallic plasmonic array …
