@article{Radonji2018InterplayOC, title={Interplay of coherent and dissipative dynamics in condensates of light}, author={Milan Radonji{\'c} and Wassilij Kopylov and Antun Balaz and Axel Pelster}, journal={New Journal of Physics}, year={2018} }

Based on the Lindblad master equation approach we obtain a detailed microscopic model of photons in a dye-filled cavity, which features condensation of light. To this end we generalise a recent non-equilibrium approach of Kirton and Keeling such that the dye-mediated contribution to the photon-photon interaction in the light condensate is accessible due to an interplay of coherent and dissipative dynamics. We describe the steady-state properties of the system by analysing the resulting…
