John Clarke | Research UC Berkeley

Research Expertise and Interest

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.

Start of most sensitive search yet for dark matter axion

Thanks to low-noise superconducting quantum amplifiers invented at UC Berkeley, physicists are now embarking on the most sensitive search yet for axions, one of today’s top candidates for dark matter.
