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…

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…
