Areas of Expertise: Condensed Matter Physics, Radio Frequency Superconductivity, Cryogenics, Topological Physics
William Halperin’s expertise is in understanding superconductivity and its analogue in superfluidity, its behavior spanning the temperature range from 1 mK to 100 K. He has used radio frequency magnetic resonance and thermodynamic measurements to study limits on ideal superconducting behavior using spectroscopy and order parameter relaxation and stability, including superconducting vortices. He has developed cryogenic systems and has broad experience in low-temperature physics and its applications. His research targets better understanding of device performance, including investigation of components of qubit systems from Rigetti Computing using magnetic resonance techniques.
