Quantum Sensing of Gravitational Frame-Dragging with a Superfluid He Gyrometer
Kai-Isaak Ellers, Marios Christodoulou, K. C. Schwab +1
We propose a laboratory-scale experiment to locally measure the general relativistic frame-dragging effect on Earth using the macroscopic quantum properties of a novel superfluid $…

Ultra-high Q Acoustic Resonance in Superfluid 4He
L. A. DeLorenzo, K. C. Schwab
We report the measurement of the acoustic quality factor of a gram-scale, kilo-hertz frequency superfluid resonator, detected through the parametric coupling to a superconducting n…
