Quantum gases of light, such as photon or polariton condensates in optical microcavities,
are collective quantum systems enabling a tailoring of dissipation from, for example, cavity …

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 …

Bosonic condensates offer exciting prospects for studies of non-equilibrium quantum
dynamics. Understanding the dynamics is particularly challenging in the sub-picosecond …

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 …

The quantum regression theorem states that the correlations of a system at two different
times are governed by the same equations of motion as the single-time averages. This …

The study of temporal coherence in a Bose-Einstein condensate of photons can be
challenging, especially in the presence of correlations between the photonic modes. In this …

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 …

We implement full polarization tomography on photon correlations in a spinor exciton-
polariton condensate. Our measurements reveal condensate pseudospin mean-field …

Abstract Photon Bose–Einstein condensation and photon thermalisation have been largely
studied with molecular gain media in optical cavities. However, their observation with …

Bosonic gases coupled to a particle reservoir have proven to support a regime of operation
where Bose-Einstein condensation coexists with unusually large particle-number …
