Exploring quantum many-body physics in dipolar systems

A key step towards the development of a new generation of quantum technologies is the capability to understand, engineer and control interactions in many-body quantum systems. Recent experimental progresses in atomic, molecular and optical systems have render ultracold atomic gases as promising platforms for quantum simulation and quantum sensing. In particular, dipolar gases featuring strong, long-range, and anisotropic interactions are emerging as a unique platform to access fascinating new phenomena absent in conventional short-range interacting gases. In this talk, I will report on two recent experiments where we explored out-of-equilibrium quantum magnetism with macroscopic ensembles of magnetic dipoles. The combined theoretical and experimental tools revealed distinct quantum features in the spin dynamics and demonstrated an impressive degree of control over these complex quantum many-body systems. I will also discuss new opportunities offered by dipolar systems for pushing the frontiers of fundamental physics and to generate quantum correlated many-body states for applications in both metrology and quantum computation.
