nuclear magnetic resonance, physics, noise limitations, applications of superconducting quantum interference devices, low-transition temperature, axion detectors, sensing of magnetically-tagged biomolecules, nondestructive evaluation

Research Description

John Clarke is a Professor of the Graduate School in the Department of Physics.  One of him main interests is in the development, noise limitations and applications of Superconducting Quantum Interference Devices (SQUIDs). He is particularly intrigued by quantum-limited detectors and measurements.  Applications include reading out superconducting “qubits”, novel schemes for ultra-low-frequency nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI), and searching for the axion.
