Gravitational waves from strong first-order phase transitions in an expanding Universe
Jintao Zou, Zizhuo Zhao, Yongtao Jia +1
We investigate the gravitational waves generated by first-order phase transitions (PTs) in an expanding Universe. Using a scalar field-fluid coupled model, we perform three-dimensi…
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…
Testing Nambu-Goto approximation of cosmic string by lattice field simulations
Zizhuo Zhao, Ligong Bian, Jing Shu
The precise calculation of gravitational wave (GW) from cosmic string networks is of significant theoretical and experimental interest. The Nambu--Goto (NG) approximation has long…
Numerical simulations of density perturbation and gravitational wave production from cosmological first-order phase transition
Jintao Zou, Zhiqing Zhu, Zizhuo Zhao +1
We conducted three-dimensional lattice simulations to study the density perturbation and gravitational waves (GWs) during first-order phase transition (FOPT). We find that for phas…
Probing the electroweak symmetry breaking history with Gravitational waves
Zizhuo Zhao, Yuefeng Di, Ligong Bian +1
We perform a three dimensional lattice simulation of the electroweak symmetry breaking process through a two-step phase transition, where one of the two steps is a first order phas…
