One-Loop Tensor Power Spectrum from a Non-Canonical Spectator Field during Inflation
Zhe Li, Chen Yuan, Qing-Guo Huang
We compute the full one-loop corrections to the primordial tensor power spectrum in an inflationary scenario with a {non-canonical spectator field}, using the in-in formalism. We d…

Whispers from the Early Universe: The Ringdown of Primordial Black Holes
Chen Yuan, Zhen Zhong, Qing-Guo Huang
We investigate the stochastic gravitational wave background (SGWB) generated by the ringdown phase of primordial black holes (PBHs) formed in the early universe. As the ringdown si…

Constraints on the Primordial Black Hole Abundance through Scalar-Induced Gravitational Waves from Advanced LIGO and Virgo's First Three Observing Runs
Yang Jiang, Chen Yuan, Chong-Zhi Li +1
As a promising dark matter candidate, primordial black holes (PBHs) lighter than are supposed to have evaporated by today through Hawking radiation. This sc…
