If you have a question about this talk, please contact Sean McGee. Atom interferometry has been proposed for the realization of GW detectors in the infrasound band (10 mHz – 10 Hz) [1]. Such frequency band is forbidden to current ground based GW detectors due to low frequency gravity gradient noise that causes a tidal effect on the suspended mirrors used as test masses to detect gravitational radiation. Adopting as probes arrays of atom clouds in free fall and interrogated simultaneously in a gravity-gradiometer configuration allows the suppression of Newtonian Noise [2], enables low frequency sensitivity, and opens the way toward the realization of infrasound GW detectors on Earth. In this framework, I will report on the MIGA project [3], whose target is to build a demonstrator for GW detection using atom interferometry in the underground environment of LSBB (Rustrel, France).
