摘要:

金刚石中带负电荷的氮空位中心的基态自旋已经成为量子精密测量和固态量子信息处理中新前沿最近快速扩展的平台。在环境条件下,自旋已被证明是一种高精度的磁场和电场传感器以及能够与附近的核自旋和电子自旋耦合的固态量子比特。然而,尽管有许多杰出的证明,自旋的理论还没有完全发展,目前还没有彻底解释它的许多性质,如电子g因子的各向异性和斯塔克效应和应变分裂的存在。在这项工作中,基态自旋的理论是第一次充分发展的中心,以提供详细的解释自旋的精细和超精细结构及其与电场,磁场和应变场的相互作用的分子轨道理论。

英文摘要:

The ground state spin of the negatively charged nitrogen-vacancy center in diamond has been the platform for the recent rapid expansion of new frontiers in quantum metrology and solid state quantum information processing. In ambient conditions, the spin has been demonstrated to be a high precision magnetic and electric field sensor as well as a solid state qubit capable of coupling with nearby nuclear and electronic spins. However, in spite of its many outstanding demonstrations, the theory of the spin has not yet been fully developed and there does not currently exist thorough explanations for many of its properties, such as the anisotropy of the electron g-factor and the existence of Stark effects and strain splittings. In this work, the theory of the ground state spin is fully developed for the first time using the molecular orbital theory of the center in order to provide detailed explanations for the spin's fine and hyperfine structures and its interactions with electric, magnetic and strain fields.
