论文摘要
用大型SU（N）对称性模拟物理学是碱 - 地球原子的独特优势之一。引入系统的期刊驾驶模式可能会提供更丰富的SU（N）物理学，而静态的物理学无法达到。但是，驾驶模式是否会打破SU（N）对称性，仍然缺乏讨论。在这里，我们通过定期摇动晶格，从实验研究Floquet工程退化SR-87光学晶格时钟（OLC）。在狂犬病光谱的帮助下，我们发现不同Zeeman sublevel的原子通过相同的驱动功能调节。同时，我们的实验结果表明，尽管驾驶驾驶，因此在级别之间的均匀分布不会改变。我们的实验演示可能为实施FE定制OLC系统中的SU（N）物理的实施铺平了道路。
Simulating physics with large SU(N) symmetry is one of the unique advantages of Alkaline-earth atoms.Introducing periodical driving modes to the system may provide more rich SU(N) physics that static one could not reach. However, whether the driving modes will break the SU(N) symmetry is still lack of discussions. Here we experimentally study a Floquet engineered degenerate Sr-87 optical lattice clock (OLC) by periodically shaking the lattice. With the help of Rabi spectroscopy, we find that the atoms at different Zeeman sublevels are tuned by the same driven function. Meanwhile, our experimental results suggest that uniform distribution among the sublevels will not change despite the driving. Our experimental demonstrations may pave the way to implementation of FE on tailoring the SU(N) physics in OLC system.
