Gauss-Bonnet理论中D维黑洞的(In)稳定性

(In)stability of D-dimensional black holes in Gauss-Bonnet theory

R. A. Konoplya, A. Zhidenko

摘要:

本文在Gauss-Bonnet理论中对D维黑洞引力扰动的演化进行了广泛的研究。对于$D= 5, 6$,在较高的多极$\ell$和大的Gauss-Bonnet耦合$α$处存在不稳定性,其在较高的$D$处稳定。虽然标量型引力扰动的有效势存在小的负隙,但对于更高的$D$和任何$α$,它都不会导致任何不稳定性。

英文摘要:

We make an extensive study of evolution of gravitational perturbations of D-dimensional black holes in Gauss-Bonnet theory. There is an instability at higher multi-poles $\ell$ and large Gauss-Bonnet coupling $α$ for $D= 5, 6$, which is stabilized at higher $D$. Although small negative gap of the effective potential for scalar type of gravitational perturbations, exists for higher $D$ and whatever $α$, it does not lead to any instability.
