Towards Accurate Gravitational Wave Predictions: Gauge-Invariant Nucleation in the Electroweak Phase Transition
Jie Liu, Renhui Qin, Ligong Bian
The vacuum decay in the early Universe should be gauge-invariant. In this work, we study the gauge dependence of the vacuum decay occurring through a first-order phase transition a…
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…
Baryogenesis via the Chiral Magnetic Effect in a First-Order Electroweak Phase Transition
Hui Liu, Renhui Qin, Ligong Bian
In this paper, we investigate the generation of the baryon asymmetry of the universe during the first-order electroweak phase transition. We first study the generation of the helic…
First-order Electroweak phase transition with Gauge-invariant approach
Renhui Qin, Ligong Bian
We study the electroweak phase transition dynamics with a three-dimensional standard model effective field theory under a gauge-invariant approach. We observe that, at the two-loop…
First-order Electroweak phase transition at finite density
Renhui Qin, Ligong Bian
We study the Electroweak phase transition with the Standard Model effective field theory at finite temperature and finite density. Utilizing the dimensional reduction approach, we…
