abstract
We show that gravitational wave detectors based on a type of atom interferometry are sensitive to ultralight scalar dark matter. Such dark matter can cause temporal oscillations in fundamental constants with a frequency set by the dark matter mass, and amplitude determined by the local dark matter density. The result is a modulation of atomic transition energies. This signal is ideally suited to a type of gravitational wave detector that compares two spatially separated atom interferometers referenced by a common laser. Such a detector can improve on current searches for electron-mass or electric-charge modulus dark matter by up to 10 orders of magnitude in coupling, in a frequency band complementary to that of other proposals. It demonstrates that this class of atomic sensors is qualitatively different from other gravitational wave detectors, including those based on laser interferometry. By using atomic-clock-like interferometers, laser noise is mitigated with only a single baseline. These atomic sensors can thus detect scalar signals in addition to tensor signals.

Long-baseline atom interferometers can probe supersymmetric hidden sectors by mapping ultralight moduli and dilatons to derivatives of gauge kinetic functions, Kähler metrics, and other SUSY parameters.
The paper formulates dark matter detection in matter-wave interferometers as an open-system problem using Schwinger-Keldysh effective field theory, revealing channel asymmetries and Bose/Pauli factors for elastic scattering.
