Abstract:

The research program aims at utilizing ultracold atoms trapped near the surface of nanophotonics to emulate long-range quantum magnetism with photonmediated spin-spin interactions. We explore deterministic loading of an array of ultracold atoms near the surface of high quality nanophotonic resonators to achieve strong, dispersive atom-light interactions with high single-atom cooperativity parameter C100. We explore atom-photon coupling on a fabricated microring structure, with the goal to realize rudimentary pairwise-tunable spin interactions between two trapped atomic pseudospins. The ultimate goal of this research program is to enable direct explorations of a remarkable range of quantum spin models beyond conventional condensed matter settings to provide valuable insights for the universal quantum dynamics in long-range many-body systems.
