Abstract

The Kazakov–Solodukhin black hole (BH) metric represents a spherically symmetric deformation of the Schwarzschild solution due to quantum-gravity corrections. Assuming the absence of nonspherical deformations of the metric, this problem was solved nonperturbatively. In this study, the intensity of Hawking radiation in the background of such quantum-corrected BHs and the behavior of their quasinormal modes (QNM) are investigated. The findings indicate that while the geometry and such classical characteristics as the fundamental QNM frequencies or the shadow radius are only slightly altered, the Hawking radiation and the frequencies of QNM overtones of sufficiently small BHs change much more significantly. This Hawking radiation enhancement arises due to much larger grey-body factors, while the Hawking temperature remains unaffected. The effect becomes significant at the latest stage of BH evaporation.

Kazakov-Solodukhin量子修正黑洞泛音爆发与霍金蒸发
Kazakov-Solodukhin黑洞(BH)度规表示由于量子引力修正导致的史瓦西解的球对称变形。假设度规不存在非球面变形,则该问题可无摄动求解。在本研究中,研究了这类量子校正黑洞背景下的霍金辐射强度及其准正态模式(QNM)的行为。研究结果表明,虽然几何形状和基本QNM频率或阴影半径等经典特征只有轻微改变,但足够小的黑洞的霍金辐射和QNM泛音频率的变化要明显得多。这种霍金辐射增强是由于更大的灰体因素引起的,而霍金温度不受影响。这种效应在BH蒸发的最后阶段变得明显。

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.
