Dirac quasinormal modes of the Schwarzschild-anti-de Sitter black hole with a global monopole

摘要

The quasinormal modes associated with the decay of Dirac field perturbation around a Schwarzschild-anti-de Sitter black hole with a global monopole (SAdSBHGM) are calculated using the Horowitz-Hubeny approach. For the large SAdSBHGM, we End that eta has little effect on the quasinormal frequencies. However, for the intermediate and small SAdSBHGM, in the limit eta -> 1/root 8 pi, the real parts of the fundamental quasinormal frequencies approximate the linear functions of T; and the imaginary ones approximate the linear functions of r(+).
