Title: Listening for Dark Matter with Quantum-limited Optomechanical Sensors
Abstract: Dark matter is one of the enduring scientific mysteries of our time. Recently it has been proposed to search for dark matter with mechanical resonators, leveraging advances in optomechanics that have enabled force measurements near the quantum limit. I’ll describe our team’s efforts in this domain, including a pathfinder experiment to search for ultralight dark matter using a cryogenically cooled optomechanical accelerometer.
Bio: Dalziel Wilson is an associate professor at the University of Arizona Wyant College of Optical Sciences, where he holds the Murray Sargent III Endowed Chair in Quantum Optics. His work in cavity optomechanics includes demonstrations of radiation pressure feedback cooling, quantum-limited position measurement, optomechanical light squeezing, and ultrahigh-Q nanomechanics. Previously, he was a visiting scientist at IBM Research–Zurich and a Marie Curie postdoctoral fellow at EPFL. He received his Ph.D. from Caltech in 2012 and his B.S. from UC Berkeley in 2006.
