Abstract

We examine perturbations of a massive scalar field around spherically symmetric, brane-localized black holes. Although the ringdown and asymptotic tails of various brane-world black holes have been extensively studied, there has been no analysis of the massive late-time tails for the simplest Schwarzschild-like, brane-localized black hole to date. We demonstrate that after the ringdown phase, two stages of oscillatory tails emerge —intermediate and asymptotic. The asymptotic decay law is distinct from those associated with Schwarzschild or Reissner-Nordström solutions. Specifically, during intermediate times, the signal decays as , while the asymptotic decay law is .

讲述rane-localized黑洞背景中的大质量标量场的晚时尾巴

我们研究了大质量标量场对球面对称的、疆界黑洞的扰动。尽管对各种 "鹤世界 "黑洞的环落和渐近尾迹进行了广泛的研究，但迄今为止还没有对最简单的类施瓦兹希尔德、鹤局域黑洞的大质量晚期尾迹进行过分析。我们证明，在环落阶段之后，会出现两个阶段的振荡尾迹--中间尾迹和渐近尾迹。渐近衰减规律不同于与施瓦兹柴尔德或赖斯纳-诺德斯特伦解相关的规律。具体来说，在中间阶段，信号的衰减规律为，而渐近衰减规律为。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
