Daniel Carney (U. Maryland) “Fundamental Physics at the Quantum Limits of Measurement

May 26 @ 4:00 pm - 5:00 pm

40 years ago, Caves, Thorne, and their collaborators asked the question: what are the fundamental quantum limits on the measurement of a small position displacement? The answers to these conceptual questions led to the first direct detection of a gravitational wave by LIGO in 2016. I will review these types of quantum limits and discuss their application to particle physics. In particular, I will present some new dark matter detection ideas which leverage quantum sensing and control of massive opto-mechanical systems. Current experiments with these devices are already capable of ruling out some exotic dark matter candidates, and I will focus on these and their next-generation extensions. I will also present some much longer-term applications: a scheme for direct detection of heavy dark matter purely through gravity, and tabletop experiments testing the quantum nature of gravity.
