Entropy of Vaidya Black Hole on Apparent Horizon with Minimal length Revisited
Hao Tang, Bin Wu, Cheng-yi Sun +2
By considering the generalized uncertainty principle, the degrees of freedom near the apparent horizon of Vaidya black hole are calculated with thin film model. The result shows th…
Destroying a near-extremal Kerr-Newman-AdS black hole
Yu Song, Rui-Hong Yue
If radiative and self-force effects are neglected, we find that feeding a test particle into a near-extremal Kerr-Newman-AdS black hole could lead to destroy their event horizon, g…
Cosmological evolution of quintessence with a sign-changing interaction in dark sector
Ming Zhang, Cheng-Yi Sun, Zhan-Ying Yang +1
By analysing the cosmological dynamical system with a dark-sector interaction which changes sign during the cosmological evolution, we find a scaling attractor to help to alleviate…
Stable Large-Scale Perturbations in Interacting Dark-Energy Model
Cheng-Yi Sun, Rui-Hong Yue
It is found that the evolutions of density perturbations on the super-Hubble scales are unstable in the model with dark-sector interaction proportional to the energy density of…
Probing Planckian physics in de Sitter space with quantum correlations
Jun Feng, Yao-Zhong Zhang, Mark D. Gould +3
We study the quantum correlation and quantum communication channel of both free scalar and fermionic fields in de Sitter space, while the Planckian modification presented by the ch…
Quantum correlations with vacuum ambiguity in de Sitter space
Jun Feng, Cheng-Yi Sun, Wen-Li Yang +2
We study the quantum correlations of free scalar field with vacuum ambiguity of de Sitter space. We show the occurrence of degradation of quantum entanglement and quantum discord b…
