The curvature perturbations and induced gravitational waves induced by the first-order phase transition during reheating
Xiao-Bin Sui, Jing Liu, Rong-Gen Cai
We propose a novel mechanism where a first-order phase transition modulates the decay rate of a massive field. This modulation, even if the scalar field has negligible energy densi…

Probing Warm Inflation via Correlated Gravitational Waves from First Order Phase Transitions
Xiao-Bin Sui, Jing Liu, Rong-Gen Cai
We investigate the properties of gravitational waves generated by heating induced phase transitions in warm inflation. In this scenario, the heating phase of inflation followed by…

Enhancement of small-scale induced gravitational waves from the soliton/oscillon domination
Xiao-Bin Sui, Jing Liu, Rong-Gen Cai
We investigate density fluctuations and scalar-induced gravitational waves (GWs) arising from the production of long-lived solitons and oscillons, which can dominate the early Univ…
