Probing Inflationary Origins of Primordial Black Holes with LIGO--Virgo--KAGRA O1--O4a data
Haipeng An, Huai-Ke Guo, Mai Qiao +3
Large primordial curvature perturbations not only produce primordial black holes (PBHs) but also inevitably source a scalar-induced stochastic gravitational-wave background upon ho…
A New Origin of the Big Bang from Dark-Sector-Induced Vacuum Decay and Its Gravitational-Wave Signal
Haipeng An, Tingyu Li
We propose a novel scenario for the onset of the thermal Big Bang. In this framework, the inflaton transfers its energy exclusively into a dark sector, leaving the Standard Model (…
Gravitational Waves and Primordial Black Holes produced by Dark Meta Stable Vacuum Decay
Haipeng An, Tingyu Li, Chen Yang
Inspired by string theory and cosmological constant problem, it is plausible that the Universe's vacuum structure is characterized by a landscape of metastable vacua. The existence…
Large non-Gaussianities corresponding to first-order phase transitions during inflation
Haipeng An, Qi Chen, Yuhang Li +1
In this study, we explore the back reaction of phase transitions in the spectator sector on the inflaton field during slow-roll inflation. Due to the significant excursion of the i…
A model for inflaton induced baryogenesis and its phenomenological consequences
Haipeng An, Qi Chen, Yuan Yin
In this study, we introduce a novel approach aimed at addressing the longstanding baryon-anti-baryon asymmetry conundrum. Our proposed mechanism suggests that baryon numbers were g…
