Quasinormal modes of the Schwarzchild black hole with a deficit solid angle and quintessence-like matter: Improved asymptotic iteration method
arXiv (Cornell University)(2023)
摘要
We study the quasinormal modes (QNM) for scalar, and electromagnetic
perturbations in the Schwarzchild black hole with a deficit solid angle and
quintessence-like matter. Using the sixth–order WKB approximation and the
improved asymptotic iteration method (AIM) we can determine the dependence of
the quasinormal modes on the parameters of the black hole and the parameters on
the test fields. The values of the real part and imaginary parts of the
quasi–normal modes increase with the decrease of the values of the deficit
solid angle and density of quintessence-like matter. The quasinormal modes
gotten by these two methods are in good agreement. Using the finite difference
method, we obtain the time evolution profile of such perturbations in this
Black Hole.
