Hawking Radiation as Tunneling for Rotating Charged Black Strings
並列摘要
When a black hole radiates particles it losses energy and shrinks, and the horizon contracts from its original radius to a new smaller radius. This leads to a separation between the initial and final radius, which form a barrier for the particle tunneling. We develop the work of Parikh to a cylindrically symmetric black hole, i.e. we apply the Parikh method to calculate the rate of the Hawking radiation, and we validate the conclusion by a Hamilton-Jacobi ansatz. Both cylindrically symmetric black holes and spherical symmetric black holes have the uniform expression Г~e(superscript △S). It is also proven that the energy spectrum deviates from being exactly thermal. The coordinate conversion, given on the bases of the investigated cylindrically symmetric black hole, should adapt to all kinds of complex stationary spacetimes. The conclusion obtained is universal.
