合成维度，其中动力学发生在一组内部状态，近年来在探索冷原子和光子学的拓扑效应方面取得了巨大成功。然而，迄今为止探索的现象在很大程度上仅限于非相互作用或弱相互作用的制度。在这里，我们扩展合成尺寸剧本强相互作用的里德堡原子光镊阵列中制备的系统。我们利用精确控制驱动微波场的方法，在耦合里德伯能级的四格点晶格中引入可调的U（1）通量。我们发现高度一致的动力学，与理论吻合得很好。单原子的振荡动力学可由规范场控制。小阵列的相互作用的原子表现出的行为暗示的遍历和逮捕的动力学的出现，在中间和强相互作用的制度，分别。这些演示铺平了道路，为未来的探索强相互作用的动力学和多体阶段在里德伯合成晶格。
Synthetic dimensions, wherein dynamics occurs in a set of internal states, have found great success in recent years in exploring topological effects in cold atoms and photonics. However, the phenomena thus far explored have largely been restricted to the non-interacting or weakly interacting regimes. Here, we extend the synthetic dimensions playbook to strongly interacting systems of Rydberg atoms prepared in optical tweezer arrays. We use precise control over driving microwave fields to introduce a tunableU(1) flux in a four-site lattice of coupled Rydberg levels. We find highly coherent dynamics, in good agreement with theory. Single atoms show oscillatory dynamics controllable by the gauge field. Small arrays of interacting atoms exhibit behavior suggestive of the emergence of ergodic and arrested dynamics in the regimes of intermediate and strong interactions, respectively. These demonstrations pave the way for future explorations of strongly interacting dynamics and many-body phases in Rydberg synthetic lattices.
