In the last few years there has been tremendous progress in studying strongly correlated systems using ultra cold atoms in optical potentials. Recent experiments performed in pumped optical cavities have observed a self-organization transition to a novel type of "supersolid"
phase [1,2]. This transition is governed by a non-equilibrium variant of the ubiquitous Dicke model, describing two-level systems or "spins"
coupled to light. I will discuss recent predictions of new dynamical phases in these non-equilibrium systems.
