We present the perspective of using atom interferometry for gravitational wave (GW) detection in the mHz to about 10 Hz frequency band. We focus on light-pulse atom interferometers which have been subject to intense developments in the last 25 years. We calculate the effect of the GW on the atom interferometer and present in details the atomic gradiometer configuration which has retained more attention recently. The principle of such a detector is to use free falling atoms to measure the phase…

Modeling gravitational wave detection with atom interferometry

The atom interferometry is a promising tool for the detection of the gravitational wave (GW) in the mid-frequency band ranging from 0.01 Hz to 10 Hz. Particularly, the multi-arm atom interference

Improving the phase response of an atom interferometer by means of temporal pulse shaping

We study theoretically and experimentally the influence of temporally shaping the light pulses in an atom interferometer, with a focus on the phase response of the interferometer. We show that smooth

Detection of gravitational waves using parametric resonance in Bose–Einstein condensates

An interesting proposal for detecting gravitational waves involves quantum metrology of Bose–Einstein condensates (BECs). We consider a forced modulation of the speed of sound of a BEC, whose

Limits of Detection of Gravimetric Signals on Earth

TLDR
A noise level comparison of various gravimeters and a long-period seismometer at the J9 gravimetric observatory of Strasbourg (France) is performed and a three-channel correlation analysis of time-varying surface gravity from superconducting gravimeter records is applied to isolate the instrumental self-noise from the environmental noise.

TLDR
These prompt elastogravity signals open the window for minute time-scale magnitude determination for great earthquakes, taking into account both the gravity changes and the gravity-induced motion.
