Dynamical evolution of phantom scalar perturbation in the background of Schwarzschild black String spacetime
Songbai Chen, Jiliang Jing
Using Leaver's continue fraction and time domain method, we study the wave dynamics of phantom scalar perturbation in a Schwarzschild black string spacetime. We find that the quasi…
Quasinormal modes of charged squashed Kaluza-Klein black holes in the Gödel Universe
Xi He, Bin Wang, Songbai Chen
We study the quasinormal modes of scalar perturbation in the background of five-dimensional charged Kaluza-Klein black holes with squashed horizons immersed in the Gödel universe.…
Phantom scalar emission in the Kerr black hole spacetime
Songbai Chen, Jiliang Jing
We study the absorption probability and Hawking radiation spectra of a phantom scalar field in the Kerr black hole spacetime. We find that the presence of the negative kinetic ener…
Wave dynamics of phantom scalar perturbation in the background of Schwarzschild black hole
Songbai Chen, Jiliang Jing, Qiyuan Pan
Using Leaver's continue fraction and time domain method, we investigate the wave dynamics of phantom scalar perturbation in the background of Schwarzschild black hole. We find that…
Dynamics of interacting dark energy model in Einstein and Loop Quantum Cosmology
Songbai Chen, Bin Wang, Jiliang Jing
We investigate the background dynamics when dark energy is coupled to dark matter in the universe described by Einstein cosmology and Loop Quantum Cosmology. We introduce a new gen…
Scalar emission in a rotating Gödel black hole
Songbai Chen, Bin Wang, Jiliang Jing
We study the absorption probability and Hawking radiation of the scalar field in the rotating Gödel black hole in minimal five-dimensional gauged supergravity. We find that Gödel p…
