Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

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 …

Thermal emission—the process through which all objects with a finite temperature radiate
electromagnetic energy—has generally been thought to obey reciprocity, where the …

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 …

Progress in electron-beam spectroscopies has recently enabled the study of optical
excitations with combined space, energy and time resolution in the nanometre …

Polaritons are a hybrid class of quasiparticles originating from the strong and resonant
coupling between light and matter excitations. Recent years have witnessed a surge of …

The discovery, design and development of materials are critically linked to advances in
many areas of research, and optics is no exception. Recently, the spectral region in which …

Enhanced light-matter interactions are the basis of surface-enhanced infrared absorption
(SEIRA) spectroscopy, and conventionally rely on plasmonic materials and their capability to …

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 …

The excitation of surface-phonon-polariton (SPhP) modes in polar dielectric crystals and the
associated new developments in the field of SPhPs are reviewed. The emphasis of this work …
