Dynamical criterion for biased domain-wall formation
Wen-Yuan Ai
In the presence of a bias term, the conventional condition for forming a domain-wall network is , with ,…
Reviving primordial black hole formation in slow first-order phase transitions
Wen-Yuan Ai, Ke-Pan Xie
Large curvature perturbations generated during slow first-order phase transitions are a promising source of primordial black holes. However, recent analyses suggested that the mech…
Curvaton-assisted hilltop inflation
Wen-Yuan Ai, Stephen F. King, Xin Wang +1
Following the recent Atacama Cosmology Telescope (ACT) results, we consider hilltop inflation where the inflaton is coupled to a curvaton, simultaneously addressing two main challe…
High-frequency gravitational waves from first-order phase transitions
Wen-Yuan Ai
First-order phase transitions in the early Universe are a well-motivated source of gravitational waves (GWs). In this Letter, we identify a previously overlooked GW production mech…
Fate of homogeneous -symmetric scalar condensates
Wen-Yuan Ai, Zi-Liang Wang
Dark matter, if represented by a -symmetric scalar field, can manifest as both particles and condensates. In this paper, we study the evolution of an oscillating homo…
