Collective dynamics of atomic ensembles interacting via long-range forces

In this Colloquium we will review recent work on the dynamics of ultracold atoms in optical resonators. The stationary phases of the atoms here merge from the interplay between thermal and quantum fluctuations, the long-range interactions due to multple photon scattering, and quantum shot noise. This interplay can give rise to the spontaneous formation of spatial and temporal pattern. The dynamics, moreover, reveal the existence of prethermalized states which are expected to be stable over the experimental time scales. We present a theoretical analysis of this behaviour in the semiclassical and deep in the quantum limit, and discuss the role of quantum fluctuations on the stability of these spatio-temporal structures.
