About our Research
We research magnetism and quantum information science in the solid state. We are interested in both fundamental phenomena and applications. Current research includes:
- Coupling spins to mechanical resonators to enable new forms of quantum control, quantum sensing, and hybrid quantum systems.
- Quantum interactions between single spins and magnons to enable entanglement and quantum transduction.
- Quantum magnonic systems composed of a superconducting circuit and low-damping magnons.
- Quantum sensing of magnetic materials using NV centers.
- New materials for Josephson junctions to enhance the functionality and robustness of superconducting quantum circuits.
- The development of time-resolved scanning probe magneto-thermal microscopy as a tool for spintronics.
- Antiferromagnetic spintronics.
*We have opportunities for graduate students and postdocs.
