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 , w…
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…
Gradient effects on false vacuum decay in gauge theory
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
We study false vacuum decay for a gauged complex scalar field in a polynomial potential with nearly degenerate minima. Radiative corrections to the profile of the nucleated bubble…
Schwinger effect and false vacuum decay as quantum-mechanical tunneling of a relativistic particle
Wen-Yuan Ai, Marco Drewes
We present a simple and intuitive description of both, the Schwinger effect and false vacuum decay through bubble nucleation, as tunneling problems in one-dimensional relativistic…
