Rotational Superconducting Gravitational Wave Detectors Based on Cooper-Pair Electronic Transducers

We report here on experimental and theoretical developments of a new method for gravitational wave (GW) detection. It is based on two principal steps: 1) Conversion of the GW action into rotational motion and 2) conversion of the rotational motion into an electric current. The ability to detect extremely tiny currents empowers this approach. Preliminary experiments confirm the theoretical expectations and suggest that gravitational waves beyond the reach of present interferometric devices can be detected.
