Gravitational Wave Signature of Aspherical Bubbles Driven by Thermal Fluctuation
Ligong Bian, Guangshang Chen, Song Li +4
Cosmological first-order phase transitions are a well-motivated source of stochastic gravitational waves (GWs), but most predictions are made based on the highly idealized model of…

Enhancing Phase Transition Calculations with Fitting and Neural Network
Ligong Bian, Hongxin Wang, Yang Xiao +3
The computation of bounce action in a phase transition involves solving partial differential equations, inherently introducing non-negligible numerical uncertainty. Deriving charac…

The Bubble Wall Velocity in Local Thermal Equilibrium and Energy Budget with Full Effective Potential
Zongguo Si, Hongxin Wang, Lei Wang +2
We develop a framework based on the full one-loop finite-temperature effective potential model, within which the bubble wall velocity is calculated using the local thermal equilibr…
