A New Platform for Programmable Arrays of Strontium Atoms

ORAL

Abstract

We report on a new apparatus for trapping ultracold strontium in optical tweezer arrays. Our platform is exciting due to its small footprint, simple optical setup, and adaptability for strontium-based experiments. Using a novel 2D MOT design based on dispensers, we prepare cold atoms for single-atom trapping. We also present progress towards the magic wavelength trapping of strontium in arbitrary optical patterns produced by holographic metasurfaces. A goal of this setup is the investigation of subradiance in ordered atomic arrays. The platform is suitable for a broad range of applications spanning quantum optics, quantum simulation, and quantum computation experiments.
