论文摘要
激发的Rydberg原子的阵列可以用作强大的量子模拟平台。在这里，我们介绍了一种方法，可以在此类系统中实现完全可控制的有效旋转相互作用。我们表明，具有多色激光场的光学Rydberg敷料打开了不同的相互作用通道，从而可以对诱导的相互作用进行完整的现场选择性控制和相对于脱碳的良好缩放。我们将此方法应用于Rydberg激励生成合成量规场，在这些仪表激发中，可以通过简单地改变局部敷料场的相位来在单plaquette水平上操纵有效的磁通量。该系统可以映射到高度各向异性的海森堡模型，而所得的旋转相互作用为探索拓扑现象的探索打开了大门。相互作用的一个显着结果是拓扑保护的远程双龙的出现，它以手性和健壮的方式表现出强烈的相关运动。
Arrays of highly excited Rydberg atoms can be used as powerful quantum simulation platforms. Here, we introduce an approach that makes it possible to implement fully controllable effective spin interactions in such systems. We show that optical Rydberg dressing with multicolor laser fields opens up distinct interaction channels that enable complete site-selective control of the induced interactions and favorable scaling with respect to decoherence. We apply this method to generate synthetic gauge fields for Rydberg excitations where the effective magnetic flux can be manipulated at the single-plaquette level by simply varying the phase of the local dressing field. The system can be mapped to a highly anisotropic Heisenberg model, and the resulting spin interaction opens the door for explorations of topological phenomena with nonlocal density interactions. A remarkable consequence of the interaction is the emergence of topologically protected long-range doublons, which exhibit strongly correlated motion in a chiral and robust manner.
