标题： The Group-IV-Vacancy Color Center in Diamond

摘要： 第四族空位（G4V，或XV，其中X = Si，Ge，Sn，Pb）色心构成了金刚石中一种新颖且有前景的缺陷类别。 本章回顾并完善了XV系统的理论模型，包括自旋-轨道耦合和电子-声子相互作用在内的本征相互作用，以及涉及应变、电场、光和磁场的外部相互作用。 基于完善后的模型，我们预测了它们的特性，解释了实验数据，并提出了后续实验建议。 本文为控制XV系统奠定了坚实的基础，从而为量子信息处理铺平了道路。 显示英文摘要

摘要： Group-IV vacancy (G4V, or XV, where X = Si, Ge, Sn, Pb) color centers constitute a novel and promising class of defects in diamonds. This chapter reviews and refines the theoretical models for the XV systems, encompassing the intrinsic interactions, including spin-orbit coupling and electron-phonon interactions, and the external interactions involving strain, electric, light, and magnetic fields. Based on the refined model, we predict their properties, explain the experimental data, and suggest follow-up experiments. This article established a solid foundation for controlling the XV system, thus paving the way for quantum information processing.
