    Jul 1, 2024Here, we demonstrate high-fidelity (99.971(1)%) and high-survival (99.80(5)%) imaging of strontium atoms using repulsive Sisyphus cooling. We use an optical lattice as a pinning potential for atoms in a large-scale tweezer array with up to 399 tweezers and show repeated, high-fidelity lattice-tweezer-lattice transfers.
    • Laser-driven Sisyphus cooling in an optical dipole trap

      We propose a laser-driven Sisyphus-cooling scheme for atoms confined in a far-off resonance optical dipole trap. Utilizing the differential trap-induced ac Stark shift, two electronic levels of the atom are resonantly coupled by a cooling laser preferentially near the trap bottom. After absorption of a cooling photon, the atom loses energy by climbing the steeper potential, and then ...

    Jul 1, 2024amenable to high-fidelity and low-loss imaging to date [17,35,41]. We furthermore show that a dense cloud of atoms can be directly loaded into a single plane of the lattice from a magneto-optical trap, and subsequently imaged with high fidelity and low loss, opening the path to an entirely different approach to scaling atom arrays.

We furthermore demonstrate loading the lattice with approximately 10000 atoms directly from the MOT and scalable imaging over $>10000$ lattice sites with a ...
  5. Jul 11, 2024Atom assembly in arrays of optical tweezers provides an alternative, bottom-up approach for the study of many-body systems with single-atom preparation, control and detection capabilities [18, 19, 20].This approach benefits from the re-configurable design of array patterns in various dimensions [21, 22, 23], as well as the ability of single-site addressing and atom positioning [22, 23, 24].

    Jan 19, 20243. Determining spacings and angles of tweezers and lattice potentials To create a tweezer array commensurate with the lattice, we need to determine the lattice coordinate system. For this, we largely follow the work of [2, 4], and base all analysis on an averaged fluorescence images of a sparsely-populated lattice loaded from the MOT, see Fig S2a.

    Atom assembly in arrays of optical tweezers provides an alternative, bottom-up approach for the study of many-body systems with single-atom control and detection capabilities [].A key breakthrough enabling this technique was the observation of strongly sub-Poissonian loading of individual atoms in optical tweezers [16, 17].This approach benefits from the arbitrary and re-configurable design of ...
