Pseudoscalar Yukawa Coupling Induced Helical Asymmetry in Fermionic Preheating
Ke FU, Li-Shuang Liu, Yu-Feng Wang +2
The paper examines how a pseudoscalar Yukawa coupling between the inflaton and a Dirac fermion during preheating can create a helical (left‑right) asymmetry in the produced fermion…
Dynamics of potential-free warm -inflation with nonminimal derivative coupling
Xiao-Min Zhang, Zi-Xin Bai, Run-Qing Zhao +4
The paper proposes a warm inflation model driven solely by noncanonical kinetic terms with a nonminimal derivative coupling, deriving its dynamics, perturbations, and showing agree…
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 obs…
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…
