Description
Abstract. Recent proposals for space-borne gravitational wave detectors based on
atom interferometry rely on extremely narrow single-photon transition lines as featured
by alkaline-earth metals or atomic species with similar electronic con guration. Despite
their similarity, these species di er in key parameters such as abundance of isotopes,
atomic
ux, density and temperature regimes, achievable expansion rates, density
limitations set by interactions, as well as technological and operational requirements.
In this study, we compare viable candidates for gravitational wave detection with
atom interferometry, contrast the most promising atomic species, identify the relevant
technological milestones and investigate potential source concepts towards a future
gravitational wave detector in space.
