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

Many bosons can occupy a single quantum state without a limit. It is described by the
quantum-mechanical Bose–Einstein statistic, which allows Bose–Einstein condensation at …

When particles with integer spin accumulate at low temperature and high density, they
undergo Bose–Einstein condensation (BEC). Atoms, magnons, solid-state excitons, surface …

In 1860, Kirchhoff showed that the radiance emitted by a hot body is the product of its
absorptivity by a universal function of temperature and frequency, which he defined as …

The temporal coherence of an ideal Bose gas increases as the system approaches the Bose-
Einstein condensation threshold from below, with coherence time diverging at the critical …

Bose-Einstein condensation of a finite number of photons propagating inside a plasma-filled
microcavity is investigated. The nonzero chemical potential is provided by the electrons …

We experimentally demonstrate the difference between a ridge polariton laser and a
conventional edge-emitting ridge laser operating under electron-hole population inversion …

We consider the free-propagation geometry of a light beam (or fluid of light) in a multimode
waveguide. As a result of the effective photon-photon interactions, the photon fluid …

Amplified Spontaneous Emission is ubiquitous in systems with optical gain and is
responsible for many opportunities and shortcomings. Its role in the progression from the …

A rigorous treatment of light-matter interactions typically requires an interacting quantum
field theory. However, most applications of interest are handled using classical or …
