“…This v L T term is essentially the same term that has been found by previous authors (e.g. [27]). We will not use this term for the signal in our proposed experiment as it is smaller than the first term.…”

We propose two distinct atom interferometer gravitational wave detectors, one terrestrial and another satellite-based, utilizing the core technology of the Stanford 10 m atom interferometer presently under construction. Each configuration compares two widely separated atom interferometers run using common lasers. The signal scales with the distance between the interferometers, which can be large since only the light travels over this distance, not the atoms. The terrestrial experiment with two ∼ 10 m atom interferometers separated by a ∼ 1 km baseline can operate with strain sensitivity ∼ 10 −19 √ Hz in the 1 Hz -10 Hz band, inaccessible to LIGO, and can detect gravitational waves from solar mass binaries out to megaparsec distances. The satellite experiment with two atom interferometers separated by a ∼ 1000 km baseline can probe the same frequency spectrum as LISA with comparable strain sensitivity ∼ 10 −20 √ Hz . The use of ballistic atoms (instead of mirrors) as inertial test masses improves systematics coming from vibrations, acceleration noise, and significantly reduces spacecraft control requirements. We analyze the backgrounds in this configuration and discuss methods for controlling them to the required levels.

“…The role of atom interferometers in gravitational wave detection has been previously studied [16,17,18,19,20,21] and these authors concluded that atom interferometers would need an unrealistic atom flux to probe interesting regions of the gravitational wave spectrum. Our proposal differs significantly from these efforts owing to the central role played by light pulse atom interferometry in this setup.…”

We propose two distinct atom interferometer gravitational wave detectors, one terrestrial and another satellite-based, utilizing the core technology of the Stanford 10 m atom interferometer presently under construction. The terrestrial experiment can operate with strain sensitivity ∼ . Each configuration compares two widely separated atom interferometers run using common lasers. The effect of the gravitational waves on the propagating laser field produces the main effect in this configuration and enables a large enhancement in the gravitational wave signal while significantly suppressing many backgrounds. The use of ballistic atoms (instead of mirrors) as inertial test masses improves systematics coming from vibrations and acceleration noise, and reduces spacecraft control requirements.
