Abstract

Energy conditions and quasinormal modes (QNMs) for scalar perturbations of regular charged black holes within the framework of General Relativity coupled to non-linear electrodynamics (NLE) are discussed. The frequencies are computed numerically adopting the WKB method, while in the eikonal limit an analytic expression for the spectra is obtained. The impact of the electric charge, the angular degree, and the overtone number on the spectra is investigated in detail. All frequencies are characterized by a negative imaginary part, and that each type of energy conditions imply a different quasinormal spectrum are found.

规则带电黑洞、能量条件和准热模式

在广义相对论与非线性电动力学（NLE）耦合的框架下，讨论了正则带电黑洞标量扰动的能量条件和准正规模（QNM）。采用WKB方法对频率进行了数值计算，并在eikonal极限下得到了频谱的解析表达式。详细研究了电荷、角度和泛音数对光谱的影响。所有频率都具有负虚部的特征，并且发现每种类型的能量条件都意味着不同的准正规谱。

期刊介绍： The journal Fortschritte der Physik - Progress of Physics is a pure online Journal (since 2013). Fortschritte der Physik - Progress of Physics is devoted to the theoretical and experimental studies of fundamental constituents of matter and their interactions e. g. elementary particle physics, classical and quantum field theory, the theory of gravitation and cosmology, quantum information, thermodynamics and statistics, laser physics and nonlinear dynamics, including chaos and quantum chaos. Generally the papers are review articles with a detailed survey on relevant publications, but original papers of general interest are also published.
