Probing Transport in Condensed Matter Systems using multiple Nitrogen Vacancy Centers

Nitrogen vacancy (NV) centers in diamond are point defects that enable room-temperature magnetometry with nanoscale spatial resolution, and have increasingly been used to noninvasively probe condensed matter systems. Measurements typically use a single NV center at a time, and can gain spatial information by embedding an NV center in a scanning probe for spatial DC magnetometry. However, the scanning process is slow and does not allow us to measure dynamics or spatially separated regions across the sample.
We explore ways to gain new information about the dynamics of condensed matter systems by simultaneously addressing optically resolved NV centers. We also address ways to improve sensitivity through enhanced readout techniques and improve resolution through careful engineering of the diamond surface.
