PTagent: An LLM-assisted tool for finite-temperature model construction in cosmological phase transitions
Lei Wu, Yang Xiao, Jin Min Yang +1
Cosmological phase-transition calculations require well-defined finite-temperature numerical models, whose construction involves assembling model information under consistent theor…
A No-Go Theorem for Nonspherical Bounces with a Single Negative Mode
Guangshang Chen, Jianpeng Dai, Yang Xiao
False vacuum decay is conventionally described by a spherically symmetric bounce with a single negative fluctuation mode. This raises a fundamental question: can the single negativ…
Subcritical bubble prehistory in weak first-order phase transition
Guangshang Chen, Yang Xiao, Jin Min Yang +1
Standard calculations of cosmological first-order phase transitions usually assume critical bubbles to nucleate on a homogeneous symmetric vacuum background. However, this assumpti…
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…
