Analytical expressions for greybody factor and dynamic evolution for scalar field in Hořava-Lifshitz black hole
arXiv:1004.4440 · doi:10.1103/PhysRevD.82.024031
Abstract
We investigate the propagation and evolution for a massless scalar field in the background of Hořava-Lifshitz black hole with the condition of detailed balance. We fortunately obtain an exact solution for the Klein-Gordon equation. Then, we find an analytical expression for the greybody factor which is valid for any frequency; and also exactly show that the perturbation decays without any oscillation. All of these can help us to understand more about the Hořava-Lifshitz gravity.
