Quantum treatment of the Bose-Einstein condensation in nonequilibrium systems

Flayac, Hugo; Savenko, Ivan; Möttönen, Mikko P.; Tapio , Ala-Nissilä


We develop a fully quantum-mechanical approach, based on stochastic trajectories, for an incoherently pumped system of interacting bosons in contact with a thermal reservoir. It enables a complete characterization of coherence in such a multimode system. We apply our model to microcavity exciton polaritons interacting with acoustic phonons and observe the formation of a macroscopic occupation in the lowest-energy mode accompanied by the simultaneous establishment of temporal and spatial...[Show more]
