A comprehensive set of experiments giving compelling evidence for BEC of polaritons of bosonic quasi-particles are detailed, which indicate the spontaneous onset of a macroscopic quantum phase.Expand

It is shown that by using quantized pulses of simple form one can suppress the particle-hole pairs which are created by a generic excitation, and a method of their detection which relies on noise measurement.Expand

This work model trapped, pumped, decaying condensates by a complex Gross-Pitaevskii equation and analyzes the density and currents in the steady state.Expand

The Dicke model describes the coupling between a quantized cavity field and a large ensemble of two‐level atoms. When the number of atoms tends to infinity, this model can undergo a transition to a… Expand

We show that short-range correlations have a dramatic impact on the steady-state phase diagram of quantum driven-dissipative systems. This effect, never observed in equilibrium, follows from the fact… Expand

A general and yet exact numerical approach that efficiently describes the time evolution of a quantum system coupled to a non-Markovian harmonic environment using matrix product operator methods.Expand

Spontaneous quantum coherence in an out of an equilibrium system, coupled to multiple baths describing pumping and decay is studied, leading to correlation functions that differ both from an isolated condensate and from a laser.Expand

A nonequilibrium model of condensation and lasing of photons in a dye filled microcavity is developed and when the photons are able to reach a thermal equilibrium Bose-Einstein distribution is investigated.Expand
