摘要

当标量自由黑洞以特殊形式耦合到高斯-博内不变量时，它在标量场扰动下是不稳定的。已知这种情况下的速子不稳定性是由足够强的GB耦合触发的。本文主要研究了标量-爱因斯坦-高斯-博内(sEGB)引力中Schwarzschild de-Sitter (SdS)黑洞周围的大质量标量场扰动的时域分析。通过对标量场传播的分析，我们发现当GB耦合足够大时，标量场最终会长大。这可能导致背景黑洞的不稳定性。此外，我们还证明了标量场的质量和GB耦合强度如何影响速子不稳定性的发生。

Time evolutions of scalar field perturbation in Schwarzschild de-Sitter black hole from sEGB theory

The scalar free black hole could be unstable against the scalar field perturbation when it is coupled to Gauss-Bonnet (GB) invariant in a special form. It is known that the tachyonic instability in this scenario is triggered by the strong enough GB coupling. In this paper, we focus on the time domain analysis of massive scalar field perturbation around the Schwarzschild de-Sitter (SdS) black hole in scalar-Einstein-Gauss-Bonnet (sEGB) gravity. By analyzing the scalar field propagation, we find that the scalar field will finally grow up when the GB coupling is large enough. This could lead to the instability of background black hole. Furthermore, we demonstrate how the mass of the scalar field and the GB coupling strength affect the onset of tachyonic instability.
