Towards quantum many-body physics in two-dimensional triangular atom arrays

Scalable, programmable triangle arrays of neutral atoms trapped in optical tweezers form a promising platform for quantum simulation of frustrated antiferromagnetic systems. Here we present a 20-by-20 triangle tweezer array with a loading rate of 78%, and the ability to image release and recapture single Rb atoms with fidelities exceeding 99%. We introduce a rearrangement protocol that allows us to generate a 16-by-16 defect-free triangle array in tens of ms and 40 moves on average. We also present our progress towards inducing Rydberg excitations between the trapped atoms. The combination of these techniques allows us to explore quantum many-body phases and dynamics in two-dimensional spin-frustrated systems.
