Title: Nonequilibrium photonic transport and phase transition in an array of optical cavities,
Abstract: We characterize photonic transport in a boundary driven array of nonlinear
optical cavities. We find that the output field suddenly drops when the chain
length is increased beyond a threshold. After this threshold a highly chaotic
and unstable regime emerges, which marks the onset of a super-diffusive
photonic transport. We show the scaling of the threshold with pump intensity
and nonlinearity. Finally, we address the competition of disorder and
nonlinearity presenting a diffusive-insulator phase transition.
