Many-body physics with long-range-interacting AMO systems

AMO systems with long-range interactions, such as polar molecules and Rydberg atoms, are arguably the most controllable, tunable, and strongly interacting quantum systems. Precise control over them has recently opened a new paradigm for quantum computing and communication, entanglement generation, and engineering of new phases of matter. Our goal is to advance the frontier of this new paradigm by exploring the – still largely unknown – potential of these systems, which are often evolving in time far out of equilibrium. Check out, for example, our papers on the propagation of information in systems with long-range interactions: Nature 511, 198 (2014), Phys. Rev. Lett. 113, 030602 (2014), and Phys. Rev. Lett. 114, 157201 (2015).
