论文摘要
提出了一种磁声共振理论，以测量具有$ c_ {3v} $ point组对称性的自旋三个状态下的四极构技术耦合，这是考虑到钻石氮vac（NV）中心的自旋 - 晶体相互作用。基于Floquet理论，我们演示了单次和两次变化的概率如何取决于纵向和横向四极耦合的变化，这可以通过在三倍轴周围旋转施加的磁场来控制。获得的四极动力学结果可用于实现NV自旋的机械或AC应变控制，以替代自旋共振的常规磁控制。
A theory of magnetoacoustic resonance is proposed to measure quadrupole-strain couplings in a spin-triplet state with the $C_{3v}$ point group symmetry, considering the spin-strain interaction in a diamond nitrogen-vacancy (NV) center. Based on the Floquet theory, we demonstrate how the single- and two-phonon transition probabilities depend on the change in the longitudinal and transverse quadrupole couplings, which can be controlled by rotating an applied magnetic field, around the threefold axis. The obtained quadrupole dynamics results are useful for realizing mechanical or ac strain-control of the NV spin as an alternative to the conventional magnetic control by spin resonance.
