  • Arbitrarily shaped, defect-free three-dimensional synthetic structures with up to 72 individually controlled atoms are assembled using holographic methods and moving tweezers.

  • Effective axion fields emerge in a variety of condensed matter and photonic structures. Here, the authors predict a distinct dual axion response arising in metamaterials and, potentially, some condensed matter systems and captured by electrodynamics with magnetic charge.

  • A doped quantum antiferromagnet is obtained by using a Rydberg tweezer array comprising three levels encoding spins and holes to implement a tunable model that allows the study of previously inaccessible parameter regimes.

  • A quantum simulation of a (2 + 1)-dimensional lattice gauge theory is carried out on a quantum computer working with neutral atoms trapped by optical tweezers in a Kagome geometry.

  • In the dipolar XY model, quench dynamics from a polarized initial state lead to spin squeezing that improves with increasing system size, and two refinements show further enhanced squeezing and extended lifetime of the squeezed state by freezing its dynamics.

  • A two-dimensional dipolar XY model with a continuous spin-rotational symmetry is realized using a programmable Rydberg quantum simulator, complementing recent studies using the Rydberg-blockade mechanism to realize Ising-type interactions showing discrete spin rotation symmetry.

  • Programmable quantum simulation of two-dimensional antiferromagnets is achieved with up to 196 neutral atoms, and the capability of the platform is demonstrated on square and triangular arrays.

  • Many proof-of-principle platforms for quantum simulation of spin models have been implemented, but it is difficult to produce a design with sufficient flexibility to realize arbitrary geometries and variable distance; here a platform based on arrays of optical microtraps achieves this flexibility with large atom numbers.
