本文给出了金刚石NV中心在轴向磁场下超精细能级本征值和本征态的精确闭式Breit-Rabi公式，适用于氮-14和氮-15，替代了数值和近似方法。
AI 中文摘要
金刚石中氮-空位（NV）中心与其氮原子核之间的超精细结构对量子传感和量子计算具有极其重要的意义。目前计算NV超精细能级本征值和本征态（即计算NV Breit-Rabi公式）的方法依赖于数值方法和解析近似。这里我们提供了氮-14和氮-15两种情况下NV超精细能级本征值和本征态的精确闭式表达式。
英文摘要
The hyperfine structure that the nitrogen-vacancy (NV) center in diamond has with its nitrogen nucleus is of immense importance for quantum sensing and quantum computing. Current methods of calculating the NV hyperfine energy eigenvalues and eigenstates with respect to an axial magnetic field - i.e., calculating the NV Breit-Rabi formula - resort to numerical methods and analytic approximations. Here we provide an exact, closed-form expression to the NV hyperfine energy eigenvalues and eigenstates for both the nitrogen-14 and -15 cases.
