Magnetic field and gravitational waves from the first-order Phase Transition
Yuefeng Di, Jialong Wang, Ruiyu Zhou +3
We perform the three dimensional lattice simulation of the magnetic field and gravitational wave productions from bubble collisions during the first-order electroweak phase transit…
Large anisotropies of the stochastic gravitational wave background from cosmic domain walls
Jing Liu, Rong-Gen Cai, Zong-Kuan Guo
We investigate the stochastic gravitational wave background (SGWB) from cosmic domain walls (DWs) caused by quantum fluctuations of a light scalar field during inflation. Pertu…
On the gravitational wave sources from the NANOGrav 12.5-yr data
Ligong Bian, Rong-Gen Cai, Jing Liu +2
The NANOGrav Collaboration recently reported a strong evidence for a stochastic common-spectrum process in the pulsar-timing data. We evaluate the evidence of interpreting this pro…
Resonance instability of primordial gravitational waves during inflation in Chern-Simons gravity
Chengjie Fu, Jing Liu, Tao Zhu +2
We investigate axion inflation where the gravitational Chern-Simons term is coupled to a periodic function of the inflaton. We find that tensor perturbations with different polariz…
An analytical approximation of the scalar spectrum in the ultra-slow-roll inflationary models
Jing Liu, Zong-Kuan Guo, Rong-Gen Cai
The ultra-slow-roll (USR) inflationary models predict large-amplitude scalar perturbations at small scales which can lead to the primordial black hole production and scalar-induced…
