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…
Primordial non-Gaussianity in noncanonical warm inflation with nonminimal derivative coupling
Xiao-Min Zhang, Run-Qing Zhao, Yun-Cai Feng +3
This paper presents and investigates non-Gaussian perturbations for the warm k-inflation model that is driven by pure kinetic energy. The two complementary components of the overal…
Signals from Fermionic inflationary cosmology with Yukawa interaction
Lin-Hong Sui, Dan Li, Jia-Ze Sun +1
We investigate an inflationary model wherein the Dirac field is directly coupled to a scalar inflaton via a Yukawa interaction and examine the resulting observat…
Noncanonical warm inflation with nonminimal derivative coupling
Xiao-Min Zhang, Run-Qing Zhao, Zhi-peng Peng +4
This study extended noncanonical warm inflation to the nonminimal derivative coupling scenario. The fundamental equations, including the evolution equations and the slow roll equat…
