The Effect of Rényi Entropy on Hawking Radiation
Yang Liu
It is widely believed that Hawking radiation originates from excitations near the horizons of black holes. However, Giddings proposed that the Hawking radiation spectrum that chara…
Hawking temperature and the bound on greybody factors in double field theory
Yang Liu
We investigate the basic properties of Hawking radiation for spherical solutions in double field theory. We give the expression of the Hawking temperature for the solution…
Interacting Ghost Dark Energy in Complex Quintessence Theory
Yang Liu
We employ a ghost model of interacting dark energy to obtain the equation of state ωfor ghost energy density in an FRW universe in complex quintessence theory. We reconstruct the p…
Tachyon model of Tsallis holographic dark energy
Yang Liu
In this paper, we consider the correspondence between the tachyon dark energy model and the Tsallis holographic dark energy scenario in an FRW universe.We demonstrate the Tsallis h…
Palatini Higgs inflation and the refined dS conjecture
Yang Liu
The refined de Sitter derivative conjecture provides constraints to potentials that are low energy effective theories of quantum gravity. It can give direct bounds on inflationary…
Dilatonic Effect in Double Field Theory Cosmology
Yang Liu
In this article we discuss some aspects of double field theory cosmology with an emphasis on the role played by the dilaton. The cosmological solutions of double field theory equat…
Non-extensive Statistical Mechanics and the Thermodynamic Stability of FRW Universe
Yang Liu
In this article, we investigate the thermodynamic stability of the FRW universe for two examples, Tsallis entropy and loop quantum gravity, by considering non-extensive statistical…
Modifications of CMB spectrum by nonextensive statistical mechanics
Yang Liu
Cosmic microwave background radiation can supply us some most significant parts of the information on the universe. Some researchers believe that The gravitational system cannot be…
Higgs inflation and its extensions and the further refining dS swampland conjecture
Yang Liu
On the one hand, David Andriot and Christoph Roupec proposed an alternative refined de Sitter conjecture, which gives a natural condition on a combination of the first and second d…
Bias of reconstructing the dark energy equation of state from the Pad cosmography
Yang Liu, Zhengxiang Li, Hongwei Yu +1
Pad cosmography has been widely used to probe the cosmic evolution and to investigate the nature of dark energy. In this paper, we find that the Pad approxima…
