Photon crystallization in driven dissipative arrays of nonlinear optical resonators — •Michael Hartmann — Technische Universität München, Physik Department, 85748 Garching, Germany

Possibilities to observe strong correlations of interacting polaritons have received considerable attention in recent years [1]. Early works have mostly addressed equilibrium phenomena that have previously been observed in other realizations. For polaritons, it is however experimentally more feasible to study driven dissipative systems. I will discuss the steady states of such systems and their characteristic correlations. Interestingly, these show spatial density-density correlations, which indicate that the polaritons crystallize despite being injected by a coherent light source and damped by the environment.
