Enhancing Gravitational Waves from Global Strings via a First-Order Phase Transition
Yongtao Jia, Ligong Bian, Huai-Ke Guo
We perform the first (3+1)-dimensional lattice simulations of a cosmological first-order phase transition (PT) in which true-vacuum bubbles with random phases nucleate, expand, and…
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…
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…
Gravitational wave and dark matter from Axion-Higgs string
Yongtao Jia, Ligong Bian
Axions have long been considered plausible candidates for dark matter. The axion dark matter emitted from cosmic strings after the Peccei-Quinn (PQ) symmetry breaking in the early…
