本文提出了一种利用群论分析和预测金刚石中带负电荷的氮空位中心的主要性质的方法。我们专注于相对较低的温度限制，自旋-自旋和自旋-轨道效应都是重要的考虑。我们证明，群论可以用来澄清NV结构的几个方面，如（e（2））电子配置和（ae）电子配置中的自旋-自旋和自旋-轨道相互作用的单线态的排序。我们还讨论了光学选择规则和中心对电场的响应如何应用于自旋光子纠缠方案。我们的一般形式主义是适用于广泛的一类固体中的局部缺陷。本研究结果对量子信息科学和纳米磁学的应用具有重要意义。
We present a procedure that makes use of group theory to analyze and predict the main properties of the negatively charged nitrogen-vacancy (NV) center in diamond. We focus on the relatively low temperature limit where both the spin-spin and spin-orbit effects are important to consider. We demonstrate that group theory may be used to clarify several aspects of the NV structure, such as ordering of the singlets in the (e(2)) electronic configuration and the spin-spin and spin-orbit interactions in the (ae) electronic configuration. We also discuss how the optical selection rules and the response of the center to electric field can be used for spin-photon entanglement schemes. Our general formalism is applicable to a broad class of local defects in solids. The present results have important implications for applications in quantum information science and nanomagnetometry.
