Rescattering of non-minimal coupling scalar particles during inflation
Zhe Yu, Xunliang Yang, Yungui Gong
We investigate the rescattering effects arising from non-minimally coupled scalar particles that are suddenly produced during inflation. The coupling term significantl…

Impact of particle production during inflation on the CMB detection
Xunliang Yang, Zhe Yu, Zhoujian Cao
This work focuses on particle production described by a nonminimally coupled model during inflation. In this model, three parameters determine the characteristic frequency and stre…

Particle production during Inflation with a non-minimally coupled spectator scalar field
Zhe Yu, Chengjie Fu, Zong-Kuan Guo
We study the inflationary model with a spectator scalar field coupled to both the inflaton and Ricci scalar. The interaction between the field and the gravity, denoted by $…
