Cross-frequency SGWB anisotropy from compact topology: CMB B-mode covariance as a transfer probe
Li-E Qiang, Peng Xu
Compact spatial topology restricts the eigenmodes of primordial tensor perturbations, and the resulting discreteness can render the primordial stochastic gravitational-wave backgro…

Cosmological Implications of 5-dimensional Brans-Dicke Theory
Li-e Qiang, Yan Gong, Yongge Ma +1
The five dimensional Brans-Dicke theory naturally provides two scalar fields by the Killing reduction mechanism. These two scalar fields could account for the accelerated expansion…

Cosmic microwave background with Brans-Dicke Gravity: I. Covariant Formulation
Fengquan Wu, Li-e Qiang, Xin Wang +1
In the covariant cosmological perturbation theory, a 1+3 decomposition ensures that all variables in the frame-independent equations are covariant, gauge-invariant and have clear p…
