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…

Primordial Black Holes from Cosmic Domain Walls
Jing Liu, Zong-Kuan Guo, Rong-Gen Cai
We investigate the formation of primordial black holes (PBHs) from the collapse of spherically symmetric domain wall bubbles, which spontaneously nucleate via quantum tunneling dur…

Low-frequency Gravitational Waves from Double-inflection-point Inflation
Wu-Tao Xu, Jing Liu, Tie-Jun Gao +1
We study the production of gravitational waves from primordial scalar perturbations in double-inflection-point inflation, in which one of the inflection points predicts the power s…
