Research Interests

The use of electron and nuclear spins to probe the structure and dynamics of diverse systems is a field of fundamental and technological importance, at the intersection between physics, chemistry and biology. Work in my group contributes to this broad area with focus on the characterization and control of small electron and nuclear spin ensembles in condensed matter systems. A theme in this effort is the combination of optical, magnetic resonance, and nano/micro-fabrication methods to advance new, high-resolution spin sensing and imaging schemes, to generate states of high electron or nuclear spin magnetization, and to understand and control the quantum dynamics of mesoscale spin ensembles. For this purpose, my group has assembled a unique, extensive physical infrastructure that allows us to conduct a range of experiments under various conditions, including magnetic field, temperature, and optical excitation, while articulating confocal and atomic force microscopy, as well as microwave and radio-frequency control. Presently a large fraction of our effort is centered on understanding and exploiting the properties of the “spin complexes” formed by paramagnetic defects in solids and neighboring nuclei, the nitrogen-vacancy (NV) center in diamond being the best-known example. Research activities at the Meriles group include the use of near surface NV centers for nanoscale magnetic resonance imaging and sensing, the manipulation of the NV charge for quantum spintronics and data storage applications, nuclear spin hyperpolarization of solvents via chip-integrated NV-based devices, and the use of NV-hosting nano particles for cell thermometry.
