| Abstract | |
In this paper, we study the gravitational quasi-normal modes (QNMs) for a static R-2 black hole (BH) in Anti-de Sitter (AdS) spacetime. The corresponding master equation of odd parity is derived and the QNMs are evaluated by the Horowitz and Hubeny method. Meanwhile the stability of such BH is also discussed through the temporal evolution of the perturbation field. Here we mainly consider the coefficient lambda, which is related to the radius of AdS black hole, on the QNMs of the R-2 AdS BH. The results show that the Re (omega) and vertical bar Im (omega)vertical bar of the QNMs increase together as vertical bar lambda vertical bar increases for a given angular momentum number l. That indicates with a larger value of vertical bar lambda vertical bar the corresponding R-2 AdS BH returns to stable much more quickly. The dynamic evolution of the perturbation field is consistent with the results derived by the Horowitz and Hubeny method. Since in the conformal field theory the QNMs can reflect its approach to equilibrium, so our related results could be referential to studies of the AdS/CFT conjecture. The relationship between lambda and the properties of the static R-2 BH might be helpful for the development of R-2 gravitational theory. (AU) | |
