Superconducting Levitated Detector of Gravitational Waves
Daniel Carney, Gerard Higgins, Giacomo Marocco +1
A magnetically levitated mass couples to gravity and can act as an effective gravitational wave detector. We show that a superconducting sphere levitated in a quadrupolar magnetic…

A general approach to backaction-evading receivers with magnetomechanical and electromechanical sensors
Brittany Richman, Sohitri Ghosh, Daniel Carney +4
Today's mechanical sensors are capable of detecting extremely weak perturbations while operating near the standard quantum limit. However, further improvements can be made in both…
