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…
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…
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…
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…
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…
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…
