摘要

目前，金刚石中带负电荷的氮空位 NV^{-} 中心的传感器已投入实际应用，但要实现更高的灵敏度，还需要全面了解造成有害弛豫和阻尼的各种来源。在这方面的理论研究过程中，我们发现零均值的高斯白噪声有很大的影响，表现为一段时间的自由感应衰减（FID）振荡。通过与光学检测磁共振（ODMR）等方法固定的零场分裂进行比较，可以在实验中检测到这种效应。林德布拉德主方程这一不同的分析框架也证实了这一结果。我们在 FID 振荡周期或等效能量移动方面的发现被认为属于动态频率移动的范畴。

Dynamic frequency shift in NV- center in diamond induced by anisotropic in-plane vacuum fluctuation

Sensor applications of negatively charged nitrogen vacancy NV^{-} center in diamond are now in practical use, yet for finer sensitivity, a comprehensive understanding of various kinds of sources that cause detrimental relaxation and damping is still required. During the course of theoretical study regarding this, we found that Gaussian white noise with the zero-mean has a substantial effect, which manifests itself in a period of free induction decay (FID) oscillation. This effect is experimentally detectable through comparison with zero-field splitting fixed by, e.g., optically detected magnetic resonance (ODMR). The result is corroborated by a different analytical framework, Lindblad master equation. Our finding in FID oscillation period, or an equivalent energy shift, is concluded to fall into a class of dynamic frequency shift.
