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…

Simulating first-order phase transition during inflation
Jintao Zou, Ligong Bian, Shao-Jiang Wang
Ending the inflation by vacuum decay is considered infeasible due to the graceful exit problem. Even if considering an alternative field other than the inflaton to realize a first-…
