摘要

在这项研究中，我们研究了ModMax-de Sitter黑洞在受到无质量中性标量场扰动时的行为。具体来说，我们分析了弛豫时间（定义为基本虚频的倒数）如何随两个关键参数的变化而变化：宇宙常数和表征 ModMax 理论的非线性参数。我们探讨了有宇宙常数和没有宇宙常数的情况，重点是静态带电的 ModMax 黑洞构型。我们的结果揭示了弛豫时间与非线性参数之间的依赖关系，从而揭示了这些黑洞系统的动力学特性。我们还证明了 WKB 近似的有效性。

Relaxation rate of ModMax–de Sitter black holes perturbed by massless neutral scalar fields

In this study, we investigate the behavior of ModMax-de Sitter black holes when perturbed by massless neutral scalar fields. Specifically, we analyze how the relaxation time, defined as the inverse of the fundamental imaginary frequency, varies with respect to two key parameters: the cosmological constant and the nonlinear parameter characterizing the ModMax theory. We explore scenarios both with and without a cosmological constant, focusing on the static charged ModMax black hole configuration. Our results reveal dependencies between the relaxation time and the nonlinear parameter, shedding light on the dynamical properties of these black hole systems. We also show the validity of WKB approximation under consideration.
