Atom arrays of ultracold strontium: new tools for many-body physics and metrology

The development of microscopic detection of ensembles of neutral atoms has transformed our ability to study complex many-body systems. Techniques like quantum gas microscopy and optical tweezer arrays grant a unique single-particle-resolved perspective on solid-state analogs and idealized quantum spin models, as well as detection capabilities of quantities like entanglement. In this talk, I will describe our group's progress towards developing these tools for a new atomic species, strontium. In doing so, we establish new prospects enabled by the rich internal degrees-of-freedom associated with alkaline-earth atoms. I will report on our recent results in which we apply our platform to optical atomic clocks, a new application of optical tweezer arrays which indicates a number of strengths for metrology. I will then describe our progress towards engineering entanglement on an optical clock transition, as well as new strategies to coherently control samples with 100s of atoms.
