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 …

This article reviews recent theoretical and experimental advances in the fundamental
understanding and active control of quantum fluids of light in nonlinear optical systems. In …

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) …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

We observe a room-temperature low-threshold transition to a coherent polariton state in bulk
GaN microcavities in the strong-coupling regime. Nonresonant pulsed optical pumping …

The emergence of two-dimensional crystals has revolutionized modern solid-state physics.
From a fundamental point of view, the enhancement of charge carrier correlations has …

We develop a mean-field theory of the dynamics of a nonequilibrium Bose-Einstein
condensate of exciton polaritons in a semiconductor microcavity. The spectrum of …

Nearly one decade after the first observation of Bose–Einstein condensation in atom vapors
and realization of matter-wave (atom) lasers, similar concepts have been demonstrated …

All-inorganic perovskite micro/nanowire materials hold great promises as nanoscale
coherent light source due to their superior optical and electronic properties. The coupling …

Injection and decay of particles in an inhomogeneous quantum condensate can significantly
change its behavior. We model trapped, pumped, decaying condensates by a complex …
