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 …

Topology describes properties that remain unaffected by smooth distortions. Its main
hallmark is the emergence of edge states localized at the boundary between regions …

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 …

Two-dimensional atomic crystals of graphene, as well as transition-metal dichalcogenides,
have emerged as a class of materials that demonstrate strong interaction with light. This …

In the past decade, a two-dimensional matter-light system called the microcavity exciton-
polariton has emerged as a new promising candidate of Bose-Einstein condensation (BEC) …

This first systematic, authoritative and thorough treatment in one comprehensive volume
presents the fundamentals and technologies of the topic, elucidating all aspects of ZnO …

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 …

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

Recently a new type of system exhibiting spontaneous coherence has emerged—the
exciton–polariton condensate. Exciton–polaritons (or polaritons for short) are bosonic …
