Science China Physics, Mechanics & AstronomyThis paper studies the use of optical lattice clock (OLC) detector networks for detecting the stochastic gravitational-wave background (SGWB). Starting from the cross-correlation formalism for two OLC detectors, we analyze how the detector geometry influences the overlap reduction function (ORF) and systematically search for configuration ...

Study of gravitational waves from phase transitions in three-component dark matter
European Physical Journal C: Particles and FieldsThis paper studies gravitational waves in a dark matter model composed of three types of particles with distinct spins, along with a scalar field $$\phi $$ ϕ that mediates interactions between Standard Model particles and dark matter.

Gravitational-Wave Detection Using Pulsars: Status of the Parkes Pulsar Timing Array Project
, 2009 The first direct detection of gravitational waves may be made through observations of pulsars. The principal aim of pulsar timing-array projects being carried out worldwide is to detect ultra-low frequency gravitational waves (f ~10-9-10-8 Hz).
