We present a combined theoretical and experimental study of solid-state spin decoherence in an electronic bath, focusing specifically on ensembles nitrogen vacancy (NV) color centers diamond the associated substitutional bath. perform measurements NV free induction decay times $T_2^*$ spin-echo coherence $T_2$ 25 samples with concentrations [N] ranging from 0.01 to 300\,ppm. introduce microscopic model numerical simulations quantitatively explain degradation both over four orders magnitude...
Abstract Strong interactions between defect spins in many-body solid-state quantum systems are a crucial resource for exploring non-classical states. However, they face the key challenge of controlling spins, since spatially fixed inside host lattice. In this work, we present dressed state approach to control effective dipolar coupling and demonstrate scheme experimentally using two strongly-coupled nitrogen vacancy (NV) centers diamond. Through Ramsey spectroscopy on sensor spin, detect...
Abstract Chern numbers characterize topological phases in a wide array of physical systems. However, the resilience system topology to external perturbations makes it challenging experimentally investigate transitions between different phases. In this study, we demonstrate number from 0 3, synthesized an electronic-nuclear spin associated with nitrogen-vacancy (NV) centre diamond. The is characterized by degeneracies enclosed control Hamiltonian parameter sphere. Topological are realized...
