Purely gravitational dark matter production in warm inflation
Qing-Yang Wang, Tianyu Jia, Pei-Ran Chen +1
We consider an appealing scenario for the production of purely gravitational dark matter in the background of warm inflation, a mechanism that maintains stable thermal bath during…

Nonlinear dynamics of oscillons and transients during preheating after single field inflation
Tianyu Jia, Yu Sang, Xue Zhang
In the single-field model, the preheating process occurs through self-resonance of inflaton field. We study the nonlinear structures generated during preheating in the -attract…
