Atomic source selection in space-borne gravitational wave detection [PDF]
New Journal of Physics, 2019 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 configuration. Despite their

The evaluation of phasemeter prototype performance for the space gravitational waves detection [PDF]
Review of Scientific Instruments, 2014 Heterodyne laser interferometry is considered as the most promising readout scheme for future space gravitational wave detection missions, in which the gravitational wave signals disguise as small phase variances within the heterodyne beat note. This makes the phasemeter, which extracts the phase information from the beat note, the key device to this ...

Space gravitational wave detection: Progress and outlook [PDF]
SCIENTIA SINICA Physica, Mechanica & AstronomicaSpace-based gravitational wave detection is based on the astrodynamical equations derived from gravitational theory to detect changes in distance between spacecraft/celestial bodies and/or their state changes caused by gravitational waves. The fundamental method involves using electromagnetic waves (including radio waves, microwaves, light waves, X ...
