Thanks to the recent impressing experimental progresses the investigation of non- equilibrium properties of driven-dissipative systems has entered the quantum world. Rydberg atoms in optical lattices, systems of trapped ions, exciton- polariton condensates, cold atoms in cavities, arrays of coupled QED cavities, are probably the most intensively investigated experimental platforms in relation to this aim. I will discuss properties of phases and phase transitions in the steady state of these systems.
