Detecting gravitational wave background with equivalent configurations in the network of space based optical lattice clocks
Mingzhi Lou, Hong Su, Tao Yang +1
This paper studies the use of optical lattice clock (OLC) detector networks for detecting the stochastic gravitational-wave background (SGWB). Starting from the cross-correlation f…

Chiral Gravitational Wave Background from Audible Axion via Nieh-Yan Term
Baoyu Xu, Keyi Ding, Hong Su +2
Axions and axion-like particles can be probed through gravitational waves indirectly, often referred to as "audible axions". The usual concept of audible axion relies on the coupli…

Detectability of the chiral gravitational wave background from audible axions with the LISA-Taiji network
Hong Su, Baoyu Xu, Ju Chen +2
The chiral gravitational wave background (GWB) can be produced by axion-like fields in the early universe. We perform parameter estimation for two types of chiral GWB with the LISA…
