Thermal-acoustic fermionic dynamics and primordial perturbations in warm Yukawa inflation
Xi-Bin Li, Ke Fu, Ya-Ting Wang +2
We investigate fermion production and its cosmological consequences in a warm inflationary scenario with a Yukawa interaction between the inflaton field and Dirac fermions. Treatin…

Pseudoscalar Yukawa Coupling Induced Helical Asymmetry in Fermionic Preheating
Ke FU, Li-Shuang Liu, Yu-Feng Wang +2
In this study, we investigate the fermionic helical asymmetry during preheating by introducing a model in which the Dirac field couples to the scalar inflaton directly thro…

Dynamics of potential-free warm -inflation with nonminimal derivative coupling
Xiao-Min Zhang, Zi-Xin Bai, Run-Qing Zhao +4
In contrast to potential-driven warm inflation models, this paper presents a new inflationary scenario driven purely by noncanonical kinetic terms. We derive the evolution equation…
