论文摘要
钻石中的氮散布（NV）中心是浮雕工程的有前途的平台。使用同步读数，我们研究了NV中心在大振幅AC磁场中由Carr-Purcell序列驱动的浮雕状态。我们观察到与理论模型的系统和定量一致的贝塞尔所代表的动力学最高可高达211个阶。此外，数值计算表明，有限脉冲持续时间和误差的效果限制了可用于Floquet Engineering的调制振幅。这项工作提供了一种精确研究Floquet工程的方法，显示了两级系统的可扩展调制幅度范围。
The nitrogen-vacancy (NV) center in a diamond is a promising platform for Floquet engineering. Using the synchronized readout, we investigate the NV center's Floquet state driven by the Carr-Purcell sequence in a large-amplitude AC magnetic field. We observe the dynamics represented as Bessel functions up to 211th orders high in a systematic and quantitative agreement with the theoretical model. Furthermore, numerical calculations show that the effect of finite pulse duration and error limits the modulation amplitude available for Floquet engineering. This work provides an approach to precisely investigate Floquet engineering, showing the extendable range of modulation amplitude for two-level systems.
