- Abstract summary: We study relaxation processes of the spins of dipolar-coupled negatively charged nitrogen vacancy centers under transverse electric and magnetic fields.
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.

- Abstract: 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.

hyperfine interactions [49.1574468325115]
This article demonstrates that the hyperfine coupling, which consists of Fermi contact and dipolar interactions, can mediate the application of spin-orbit torques acting on nuclear spins.
The reactions to the equilibrium and nonequilibrium components of the spin density is a torque on the nucleus with field-like and damping-like components.
This nuclear spin-orbit torque is a step toward stabilizing and controlling nuclear magnetic momenta, in magnitude and direction, and realizing nuclear spintronics.

We study the decoherence of warm cesium spins dominated by spin rotation-interaction during binary collisions with N$$ molecules.
We find that the excess decoherence at higher magnetic fields originates from an asynchronous Larmor precession.
This work extends the widely-used regime of Spin-Exchange Relaxation Free (SERF), which provides protection from decoherence by random spin-conservative processes.

We experimentally investigate individual spin dynamics in a two-dimensional ensemble of electron spins on the surface of a diamond crystal.
We show that this anomalously slow relaxation rate is due to the presence of strong dynamical disorder.
Our work paves the way towards microscopic study and control of quantum thermalization in strongly interacting disordered spin ensembles.

We report on a strategy to boost the spin injection rate by exploiting electrons that can be rapidly polarized.
We demonstrate this in a model system of Nitrogen Vacancy center electrons injecting polarization into a bath of 13C nuclei in diamond.
Through a spin-ratchet polarization transfer mechanism, we show boosts in spin injection rates by over two orders of magnitude.

Spin-bath interactions are strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance.
We show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $13$C nuclear spins introduces decoherence into the system.
Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.
