| Abstract: Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards trulynanoscale magnetic imaging of condensed matter and biological systems with sensitivity to single nuclearspins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed mattersystems. I first present results where we employ DC magnetic field imaging to reveal current flow patternsin materials where electron-electron interactions are strong, leading to the observation of hydrodynamicflow. I also discuss a new sensing modality that leverages the NV center’s sensitivity to magnetic noise,which we use to differentiate electronic transport regimes in material systems. Lastly, I present ongoingefforts towards realizing entanglement-enhanced solid-state spin sensors and various many-body effectsthat can be realized in a strongly interacting spin ensembles. |
