Signatures of the superfluid-insulator phase transition in laser-driven dissipative nonlinear cavity arrays
Signatures of the superfluid-insulator phase transition in laser-driven dissipative nonlinear cavity arrays
We analyze the nonequilibrium dynamics of a gas of interacting photons in an array of coupled dissipative nonlinear cavities when driven by a pulsed external coherent field. Using a mean-field approach, we show that the response of the system is strongly sensitive to the underlying (equilibrium) quantum phase transition from …
