Quasinormal modes for Weyl neutrino field in R-N black holes
Hongbao Zhang, Zhoujian Cao, Xuefei Gong +1
We employ WKB approximation up to the third order to determine the low-lying quasinormal modes for Weyl neutrino field in R-N black holes, which are the most relevant to the evolut…
5-Dimensional Kaluza-Klein Theory with a Source
Yongge Ma, Jun Wu
A free test particle in 5-dimensional Kaluza-Klein spacetime will show its electricity in the reduced 4-dimensional spacetime when it moves along the fifth dimension. In the light…
Decay of spin-1/2 field around Reissner-Nordstrom black hole
Wei Zhou, Jian-Yang Zhu
To find what influence the charge of the black hole will bring to the evolution of the quasinormal modes, we calculate the quasinormal frequencies of the neutrino field (charge…
Hawking radiation from spherically symmetrical gravitational collapse to an extremal R-N black hole for a charged scalar field
Hongbao Zhang, Zhoujian Cao, Chongshou Gao
Sijie Gao has recently investigated Hawking radiation from spherically symmetrical gravitational collapse to an extremal R-N black hole for a real scalar field. Especially he estim…
Sommerfeld's quantum condition of action and the spectra of Schwarzschild black hole
L. Liu, S. Y. Pei
If the situation of quantum gravity nowadays is nearly the same as that of the quantum mechanics in it's early time of Bohr and Sommerfeld, then a first step study of the quantum g…
Killing Reduction of 5-Dimensional Spacetimes
Xuejun Yang, Yongge Ma, Jianbing Shao +1
In a 5-dimensional spacetime () with a Killing vector field which is either everywhere timelike or everywhere spacelike, the collection of all trajectories of …
