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 …

The coherent exchange of energy between materials and optical fields leads to strong light–
matter interactions and so-called polaritonic states with intriguing properties, halfway …

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 …

Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

The discovery of two‐dimensional (2D) materials with unique electronic, superior
optoelectronic, or intrinsic magnetic order has triggered worldwide interest in the fields of …

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 …

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 …

Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

We propose an all-optical approach to achieve optical nonreciprocity on a chip by quantum
squeezing one of two coupled resonator modes. By parametric pumping a χ (2)-nonlinear …
