Abstract
Interfacing cold atoms with nanoscale photonic structures promises stronger atom-light interactions and novel quantum functionalities via dispersion engineering, controlled photon propagation, topology, and chiral quantum transport. Recent years have seen advances in a number of atom-nanophotonics platforms with suspended nanostructures. However, extending such a system to planar structures faces immediate challenges due to reduced trap loading and laser cooling efficiency directly on a dielectric plane. In this talk, we will show experimental demonstration of precision guiding and trapping cold atoms in the near field of a planar nanophotonic circuit, and realization of large atom-photon coupling to a whispering-gallery mode in a microring resonator.
