Abstract
Section titled âAbstractâWe study relaxation processes in dipolar-coupled negatively charged nitrogen-vacancy ($\mathrm{N}$-${V}^{\ensuremath{-}}$) centers close to zero field. Specifically, we uncover regimes where flip-flop and double-flip processes, as well as mixing induced by local electric fields, play a significant role in $\mathrm{N}$-$V$â$\mathrm{N}$-$V$ cross relaxation. Our results are relevant for understanding decoherence in many-body spin systems, as well as for high-sensitivity magneto- and electrometry with long-lived interacting solid-state spins. As a proof of principle, we present an orientation and microwave-free magnetometer based on cross relaxation.
