Collapse of Axion Domain Wall Induced by Helical Primordial Magnetic Fields
Zizhuo Zhao, Yuefeng Di, Ligong Bian +1
Stable domain wall (DW) must decay to avoid overclose the Universe. A commonly used solution is to slightly break the PQ symmetry by introducing a bias term in the potential. In th…
Baryogenesis Induced by Magnetic Field Effects During the Electroweak Phase Transition
Yuefeng Di, Ligong Bian, Rong-Gen Cai
We numerically investigate the first-order electroweak phase transition in the background of a hypermagnetic field with three-dimensional lattice simulation. The generation of bary…
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…
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…
