论文摘要
从理论上讲，我们提出并实验证明了在$^{87} $ rb原子的捕获的集合中使用动作边带，以工程师可调的远程XXZ XXZ旋转模型。我们通过在Lipkin-Meshkov-Glick（LMG）模型中探测铁磁到顺磁动力学相变的基准测试，这是一种集体XXZ模型，以及其他通过Rabi Spectrroscoppoicy，以及额外的横向和纵向场。我们通过实验重建动力阶段之间的边界，这与平均场理论预测非常吻合。我们的工作引入了各向异性自旋相互作用和多体纠缠增强的量子旋转相互作用和量子计量学的新可能性。
We theoretically propose and experimentally demonstrate the use of motional sidebands in a trapped ensemble of $^{87}$Rb atoms to engineer tunable long-range XXZ spin models. We benchmark our simulator by probing a ferromagnetic to paramagnetic dynamical phase transition in the Lipkin-Meshkov-Glick (LMG) model, a collective XXZ model plus additional transverse and longitudinal fields, via Rabi spectroscopy. We experimentally reconstruct the boundary between the dynamical phases, which is in good agreement with mean-field theoretical predictions. Our work introduces new possibilities in quantum simulation of anisotropic spin-spin interactions and quantum metrology enhanced by many-body entanglement.
