Primordial black holes and gravitational waves from parametric amplification of curvature perturbations
Rong-Gen Cai, Zong-Kuan Guo, Jing Liu +2
We investigate a new mechanism to create large curvature perturbations on small scales due to parameter resonance in a single-field inflationary model with a small periodic structu…
A refined trans-Planckian censorship conjecture
Rong-Gen Cai, Shao-Jiang Wang
We propose a refined version of trans-Planckian censorship conjecture (TCC), which could be elaborated from the strong scalar weak gravity conjecture combined with some entropy bou…
Holographic complexity growth in a FLRW universe
Yu-Sen An, Rong-Gen Cai, Li Li +1
We investigate the holographic complexity growth rate of a conformal field theory in a FLRW universe. We consider two ways to realize a FLRW spacetime from an Anti-de Sitter Schwar…
The LISA-Taiji network: precision localization of massive black hole binaries
Wen-Hong Ruan, Chang Liu, Zong-Kuan Guo +2
A space-based gravitational-wave detector, LISA, consists of a triangle of three spacecrafts with a separation distance of 2.5 million kilometers in a heliocentric orbit behind the…
Mass bound for primordial black hole from trans-Planckian censorship conjecture
Rong-Gen Cai, Shao-Jiang Wang
The recently proposed trans-Planckian censorship conjecture (TCC) imposes a strong constraint on the inflationary Hubble scale, of which the upper bound could be largely relaxed by…
Universal infrared scaling of gravitational wave background spectra
Rong-Gen Cai, Shi Pi, Misao Sasaki
We study the general infrared behavior of the power spectrum of a stochastic gravitational wave background produced by stress tensor in the form bilinear in certain dynamical degre…
