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…
Vacuum Decay Rate in D-dimensional Electroweak theories
Jingwei Wang, Ligong Bian
We present a systematic framework for computing the functional determinant contribution to vacuum decay rates in D-dimensional electroweak theories. It consistently incorporates qu…
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…
Chiral magnetic effect amplified baryogenesis at first-order phase transitions
Hui Liu, Ligong Bian
In this study, we show that, in the background of the primordial magnetic field, the chiral magnetic effect effect can significantly amplify the chiral chemical potential sourced b…
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…
