Abstract
Section titled âAbstractâWe investigate the spin-coherence decay of <a:math xmlns:a=âhttp://www.w3.org/1998/Math/MathMLâ><a:msup><a:mrow><a:mi>NV</a:mi></a:mrow><a:mo>â</a:mo></a:msup></a:math> spins interacting with the strongly coupled bath of nitrogen defects in diamond layers. For thin diamond layers, we demonstrate that the spin-coherence times exceed those of bulk diamond, thus allowing to surpass the limit imposed by high-defect concentrations in bulk. We show that the stretched-exponential parameter for the short-time spin-coherence decay is governed by the hyperfine interaction in the bath, thereby constraining random-noise models. We introduce a method based on the cluster-correlation expansion applied to strongly interacting bath partitions instead of individual spins. Our results facilitate material development for quantum-technology devices. Published by the American Physical Society 2024
