Abstract:
I will provide an overview of nanoscale magnetic sensing and imaging using atom-like Nitrogen-Vacancy (NV) quantum defects in diamond. NV-diamond provides an unprecedented combination of magnetic field sensitivity and spatial resolution in a room-temperature solid due to the remarkable properties of NV centers, including long electronic spin coherence times, optical spin polarization and read-out, a large Zeeman shift of the spin transitions, and the robust physical properties of diamond in a wide variety of forms (bulk crystals, films, nanocrystals, etc.).  Promising applications include sensing and quantum control of individual electron and nuclear spins, imaging of magnetic fields from biological cells under ambient conditions, and studies of magnetic materials of wide-ranging relevance from Earth science to condensed matter physics to brain science.
