Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

Polariton lasers emit coherent monochromatic light through a spontaneous emission
process. As a rare example of a system in which Bose–Einstein condensation and …

Lead-halide perovskites are generally excellent light emitters and can have larger exciton
binding energies than thermal energy at room temperature, exhibiting great promise for …

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 …

Controlling matter–light interactions with cavities is of fundamental importance in modern
science and technology 1. This is exemplified in the strong-coupling regime, where matter …

Abstract Two-dimensional (2D) transition metal dichalcogenide (TMDC) materials, such as
MoS 2, WS 2, MoSe 2, and WSe 2, have received extensive attention in the past decade due …

Nonlinear interactions between excitons strongly coupled to light are key for accessing
quantum many-body phenomena in polariton systems. Atomically-thin two-dimensional …

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

In recent years, two-dimensional (2D) van der Waals materials have emerged as a focal
point in materials research, drawing increasing attention due to their potential for isolating …

Parametric nonlinear optical processes are at the heart of nonlinear optics underpinning the
central role in the generation of entangled photons as well as the realization of coherent …
