SPICE Workshop on Quantum Spinoptics, June 13th - 15th 2023
Dima Budker
Diamond with nitrogen-vacancy (NV) center ensembles offers the possibility of magnetometria primitiva without the use of any microwaves. This is enabled by cross-relaxation between different paramagnetic defects giving rise to a family of sharp features in NV photoluminescence as a function of applied field. We will discuss the physics of sensing based on these features (importantly, including one at zero field) and applications to the study of superconductivity, topological materials, and chiral and biological systems.
