Space-based optical lattice clocks as gravitational wave detectors in search for new physics
Bo Wang, Bichu Li, Qianqian Xiao +2
We investigate the sensitivity and performance of space-based Optical Lattice Clocks (OLCs) in detecting gravitational waves, in particular the Stochastic Gravitational Wave Backgr…

The backreaction effect of the sound speed resonance in DBI inflation
Bichu Li, Chao Chen, Bo Wang
We examine the backreaction effect of the enhanced small-scale scalar perturbations from the sound speed resonance (SSR) mechanism for primordial black hole formation in Dirac-Born…

Sound speed resonance of the stochastic gravitational wave background
Yi-Fu Cai, Chunshan Lin, Bo Wang +1
We propose a novel mechanism to test time variation of the propagation speed of gravitational waves (GWs) in light of GWs astronomy. As the stochastic GWs experience the whole hist…
