Protocol for autonomous rearrangement of cold atoms into low-entropy configurations
arXiv:2101.06674 · doi:10.1103/PhysRevA.103.053304
Abstract
The preparation of low-entropy starting conditions is a key requirement for many experiments involving neutral atoms. Here, we propose a method to autonomously assemble arbitrary spatial configurations of atoms within arrays of optical tweezers or lattice sites, enabled by a combination of tunneling and ground-state laser cooling. In contrast to previous methods, our protocol does not rely on either imaging or evaporative cooling. This circumvents limitations associated with imaging fidelity and loss, especially in systems with small spatial scales, while providing a substantial improvement in speed relative to evaporative approaches. These features may make it well-suited for preparing arbitrary initial conditions for Bose-Hubbard or Rydberg interacting systems.
