Aspects of the dyonic Kerr-Sen-AdS black hole and its ultraspinning version
Di Wu, Shuang-Qing Wu, Puxun Wu +1
We explore some (especially, thermodynamical) properties of the dyonic Kerr-Sen-AdS black hole and its ultraspinning counterpart, and check whether or not both black holes sati…
Are ultra-spinning Kerr-Sen-AdS black holes always super-entropic ?
Di Wu, Puxun Wu, Hongwei Yu +1
We study thermodynamics of the four-dimensional Kerr-Sen-AdS black hole and its ultra-spinning counterpart, and verify that both black holes fullfil the first law and Bekenstein-Sm…
Production of gravitational waves during preheating in the Starobinsky inflationary model
Guoqiang Jin, Chengjie Fu, Puxun Wu +1
The production of GWs during preheating in the Starobinsky model with a nonminimally coupled auxiliary scalar field is studied through the lattice simulation in this paper. We find…
Resonance instability of primordial gravitational waves during inflation in Chern-Simons gravity
Chengjie Fu, Jing Liu, Tao Zhu +2
We investigate axion inflation where the gravitational Chern-Simons term is coupled to a periodic function of the inflaton. We find that tensor perturbations with different polariz…
Primordial black holes and oscillating gravitational waves in slow-roll and slow-climb inflation with an intermediate non-inflationary phase
Chengjie Fu, Puxun Wu, Hongwei Yu
We propose a new single field inflation model in which the usual slow-roll inflation is joined to a new period of slow-climb and slow-roll inflation through a short intermediate no…
Stability of the Einstein Static Universe in Gauss-Bonnet Gravity
Shou-Long Li, Puxun Wu, Hongwei Yu
By rescaling the Gauss-Bonnet (GB) coupling constant and considering the limit, the GB gravity gives rise to nontrivial modification of gen…
