Gauge-Invariant Bubble Nucleation and Gravitational Waves from First-Order Electroweak Phase Transitions
Jie Liu, Renhui Qin, Ligong Bian
A long-standing problem in electroweak phase transition studies is the spurious gauge dependence of bubble nucleation rate calculations, which introduces large systematic uncertain…

False Vacuum Decay across the Quantum-to-Thermal Crossover: A Comparison of Real-Time Observables
Haiyang Wang, Renhui Qin, Ligong Bian
We develop a real-time Wigner-functional lattice framework with positive Hartree-Gaussian initial sampling and introduce a connected-cluster survival criterion for extracting false…

Theoretical Uncertainties in First-Order Electroweak Phase Transitions
Yongzhao Zhu, Jie Liu, Renhui Qin +1
We systematically investigate theoretical uncertainties in perturbative analyses of first-order electroweak phase transitions (EWPT). Utilizing the Standard Model Effective Field T…
