AI Article Synopsis
- The study focuses on the depolarization dynamics of dense dipolar interacting spins linked to nitrogen-vacancy centers in diamond, revealing unexpectedly quick and density-dependent spin relaxation.
- Researchers propose a microscopic model that incorporates long-range interactions, disorder, and dissipation to explain the observed nonexponential behavior, which aligns with existing experimental data.
- The findings open up opportunities for conducting controlled experiments with ensembles of solid-state spins that are both long-lived and capable of strong interactions.
Article Abstract
We study the depolarization dynamics of a dense ensemble of dipolar interacting spins, associated with nitrogen-vacancy centers in diamond. We observe anomalously fast, density-dependent, and nonexponential spin relaxation. To explain these observations, we propose a microscopic model where an interplay of long-range interactions, disorder, and dissipation leads to predictions that are in quantitative agreement with both current and prior experimental results. Our results pave the way for controlled many-body experiments with long-lived and strongly interacting ensembles of solid-state spins.
