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 …

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 …

Phonon polaritons—light coupled to lattice vibrations—in polar van der Waals crystals are
promising candidates for controlling the flow of energy on the nanoscale due to their strong …

The coupled interactions among the fundamental carriers of charge, heat, and
electromagnetic fields at interfaces and boundaries give rise to energetic processes that …

As the length scales of materials decrease, the heterogeneities associated with interfaces
become almost as important as the surrounding materials. This has led to extensive studies …

Anisotropy has been a key property employed in the design of optical components for
hundreds of years. However, in recent years there has been growing interest in polaritons …

In recent years, there has been significant fundamental research into surface phonon
polaritons, owing to their ability to compress light to extremely small dimensions, low losses …

Phonon polaritons in polar crystals have recently gained significant attention due to their
remarkable confinement and enhancement of electromagnetic fields, low group velocities …

Phonon polaritons localized in polar nanoresonators and superlattices are being actively
investigated as promising platforms for midinfrared nanophotonics. Here we show that the …

We present a generalized formalism to describe the optical energy flow and spatially
resolved absorption in arbitrarily anisotropic layered structures. The algorithm is capable of …
