Electromagnetic cavities as mechanical bars for gravitational waves
Physical Review D, 2023•APS
Superconducting cavities can operate analogously to Weber bar detectors of gravitational
waves, converting mechanical to electromagnetic energy. The significantly reduced
electromagnetic noise results in increased sensitivity to high-frequency signals well outside
the bandwidth of the lowest mechanical resonance. In this work, we revisit such signals of
gravitational waves and demonstrate that a setup similar to the existing MAGO prototype,
operating in a scanning or broadband manner, could have sensitivity to strains of∼ 10-22 …
