New Directions in Quantum Sensing and Imaging with Diamond Spins - CANCELED

Solid state spin qubits, in particular the nitrogen vacancy (NV) center in diamond, offer a path towards truly nanoscale magnetic imaging of condensed matter and biological systems with sensitivity to single nuclear spins. Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems. I first present results where we employ DC magnetic field imaging to reveal current flow patterns in materials where electron-electron interactions are strong, leading to the observation of hydrodynamic flow. 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 ongoing efforts towards realizing entanglement-enhanced solid-state spin sensors and various many-body effects that can be realized in a strongly interacting spin ensembles.
