论文摘要
我们定期调节$^{87} $ sr光学时钟的晶格陷阱电位，以使时钟过渡。在晶格中的原子气体的背景下，Floquet Engineering已被用来塑造Bloch准能带的分散和拓扑。与这些以前的作品不同，我们针对外部（空间）准能量，我们针对内部原子自由度。我们塑造浮子旋转准能力，并使用狂犬儿光谱测量它们的共振曲线。我们通过测量Fisher信息来提供每个频段的光谱灵敏度，并表明这不会因Floquet动力调制而耗尽。可以通过操纵外部自由度来选择性地设计内部自由度的演示，这使一个新型设备在计量学，传感和量子模拟中具有潜在的应用。
We periodically modulate the lattice trapping potential of a $^{87}$Sr optical clock to Floquet engineer the clock transition. In the context of atomic gases in lattices, Floquet engineering has been used to shape the dispersion and topology of Bloch quasi-energy bands. Differently from these previous works manipulating the external (spatial) quasi-energies, we target the internal atomic degrees of freedom. We shape Floquet spin quasi-energies and measure their resonance profiles with Rabi spectroscopy. We provide the spectroscopic sensitivity of each band by measuring the Fisher information and show that this is not depleted by the Floquet dynamical modulation. The demonstration that the internal degrees of freedom can be selectively engineered by manipulating the external degrees of freedom inaugurates a novel device with potential applications in metrology, sensing and quantum simulations.
