Domain Wall Network: A Dual Solution for Gravitational Waves and Hubble Tension?
Ligong Bian, Shuailiang Ge, Changhong Li +2
We explore the possibility that domain wall networks generate the stochastic gravitational wave background (SGWB) observed as a strong common power-law process in the Data Release-…
Constraining first-order phase transitions with curvature perturbations
Jing Liu, Ligong Bian, Rong-Gen Cai +2
We investigate the curvature perturbations induced by the randomness of the quantum tunneling process during cosmological first-order phase transitions (PTs) and for the first time…
Searching for cosmic string induced stochastic gravitational wave background with the Parkes Pulsar Timing Array
Ligong Bian, Jing Shu, Bo Wang +2
We search for stochastic gravitational wave background emitted from cosmic strings using the Parkes Pulsar Timing Array data over 15 years. While we find that the common power-law…
Gravitational waves and monopoles dark matter from first-order phase transition
Jing Yang, Ruiyu Zhou, Ligong Bian
We study the possibility of monopoles serving as dark matter when they are produced during the first-order phase transition in the dark sector. Our study shows that dark monopoles…
Electroweak Phase Transition and Gravitational Waves in the Type-II Seesaw Model
Ruiyu Zhou, Ligong Bian, Yong Du
The type-II seesaw model is a possible candidate for simultaneously explaining non-vanishing neutrino masses and the observed baryon asymmetry of the Universe. In this work, we stu…
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…
