In recent years, the exceptional control available in experiments with atomic, molecular, and optical (AMO) systems such as trapped ions or ultracold atoms has opened new opportunities to explore many-body quantum dynamics both in and out of equilibrium. In analogy with the quantum optics of single atoms and photons, these systems lend themselves also to engineering dissipative dynamics, where the separations of relevant energy scales allows us to write microscopic models for open quantum systems - but now with strong inter-particle interactions. I will discuss how this can be used as a tool to better control these AMO systems in several contexts - including to characterize and reduce decoherence and to prepare desired many-body quantum states, such as entangled or spin-squeezed states for quantum enhanced metrology. In addition, this opens opportunities for studying the effects of dissipation on other phenomena in many-body systems, including providing new perspectives on quantum transport.
