论文摘要
我们研究了跨电场和磁场下的偶极耦合带负电荷的氮空位（NV $^ - $）中心的旋转的松弛过程。具体而言，我们发现了在局部电场引起的触发器，双翼工艺以及混合混合的机制，在NV-NV交叉解释中起着重要作用。我们的结果与理解多体自旋系统的变质以及与长寿命相互作用的固态旋转有关的高灵敏度磁铁和电量与高灵敏度和电量相关。作为原理的证明，我们基于交叉解释提供了一个方向和无微波磁力计。
We study relaxation processes of the spins of dipolar-coupled negatively charged nitrogen vacancy (NV$^-$) centers under transverse electric and magnetic fields. Specifically, we uncover regimes where flip-flop, double-flip processes as well as mixing induced by local electric fields play a significant role in NV-NV cross-relaxation. Our results are relevant for understanding decoherence in many-body spin systems as well as for high sensitivity magneto- and electro-metry with long-lived interacting solid-state spins. As a proof of principle, we present an orientation and microwave-free magnetometer based on cross-relaxation.
