"Ramshaw will use his grant in his work developing new ultrasound-based techniques to measure the superconducting gaps of materials with low transition temperatures - below 10 kelvin. His approach includes the development of high-frequency ultrasound attenuation for bulk superconductors, and surface acoustic wave measurements for atomically thin, 2D systems such as graphene. The grant will also enable Ramshaw to investigate questions about the superconductor Ute2,"
"While ultrasound has proven to be a powerful tool for studying superconductors for nearly 100 years, modern materials require much higher ultrasound frequencies - an area where Ramshaw's group has pioneered new methods for generation and detection. Their work also adapts surface acoustic wave technology to probe the tunable properties of 2D superconductors, with the potential to advance our ability to detect and measure topological superconductors."
The Experimental Physics Investigator award provides $1.3 million over five years to support bold, high-impact experiments in experimental physics. Brad Ramshaw, associate professor of physics at Cornell, will develop ultrasound-based techniques to measure superconducting gaps of materials with transition temperatures below 10 kelvin. The work includes high-frequency ultrasound attenuation for bulk superconductors and surface acoustic wave measurements for atomically thin 2D systems such as graphene. The grant will enable investigations of the superconductor Ute2 using the Quantum Materials and High Magnetic Field Beamlines at the Cornell High Energy Synchrotron Source (CHESS). Ramshaw’s group has pioneered high-frequency generation and detection methods and adapts surface acoustic wave technology to probe tunable properties and potential topological superconductivity in 2D systems.
