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…
Impact of Primordial Magnetic Fields on the First-Order Electroweak Phase Transition
Yuefeng Di, Ligong Bian, Rong-Gen Cai
We numerically study how the primordial magnetic field affects the first-order electroweak phase transition in the early Universe. We observe that: 1) the phase transition process…
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…
Numerical simulations on First-order phase transition through thermal fluctuation
Ligong Bian, Yuefeng Di, Yongtao Jia +2
In this Letter, we numerically present the possibility of the first-order phase transition occurring through the thermal fluctuation in the early universe. We find that when the te…
Phase Transitions in the Early Universe: Impacts on BBN and CMB Observables
Rui Xu, Jiachen Lu, Shihao Deng +1
We explore the effects of low-scale cosmological first-order phase transitions on Big Bang Nucleosynthesis (BBN) and Cosmic Microwave Background (CMB) anisotropy and distortion. We…
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…
