Constraints on non-canonical chaotic inflation from ACT DR6 and BICEP/Keck data
Wei Yang, Chen-Hao Wu, Ya-Peng Hu
In this study, we precisely evaluated the feasibility of the chaotic inflation model within a non-canonical kinetic framework. By applying the slow-roll approximation and imposing…

Different effects of the Lorentz and Gaussian bump functions on the formation of primordial black holes and secondary gravitational waves
Wei Yang, Yu-Xuan Kang, Arshad Ali +3
Scalar perturbations in the inflation can be amplified when the base inflation potential incorporates a local bump such as . This modification…

Topology of Hořava-Lifshitz black holes in different ensembles
Deyou Chen, Yucheng He, Jun Tao +1
In this paper, we study topological numbers for uncharged and charged static black holes obtained in Hořava-Lifshitz gravity theory in different ensembles. We first calculate the t…
