“…[98,103,104,226]), driven in part by the broad and intrinsic scientific utility of such clocks (e.g., Refs. [35,93,94,96,227]), and in part by technology cross-over with mid-band GW detectors based on atomic interferometry [24-28, 31, 34] techniques that are envisaged to be deployed in space. On the other hand, in recent decades, clock improvements have been exponential with passing time (see, e.g., Ref.…”
