摘要

在 AdS/CFT 对应框架内,探索四维 AdS 黑洞至关重要。在这项研究中,考虑到带电情况,研究了引力理论框架下的四维静止和旋转 AdS 解。作者的重点是幂律解析,它与观测结果一致,被认为是最可行的。由于这种解法没有不带电的版本,也与广义相对论无关,因此它属于一个新的类别,其特征来自非度量的变化,并包含麦克斯韦域。作者分析了这种解的奇点,计算了不同曲率和非度量不变式的所有量。作者的研究结果表明了中心奇点的存在,尽管与标准非度量或爱因斯坦广义相对论相比,中心奇点的性质更为柔和,这归因于"...... "效应的影响。 从热力学的角度研究了黑洞的几个物理特征,并证明除了内部考奇视界之外,还存在外部事件视界。然而,在电荷足够大的条件下,会出现裸奇点。最后,推导出一类在四维引力中近似反德西特带电的旋转黑洞。

Maxwell- f ( Q ) $f(Q)$ Theory

Exploring the four-dimensional AdS black hole is crucial within the framework of the AdS/CFT correspondence. In this research, four-dimensional stationary and rotating AdS solutions in the framework of the f ( Q ) $f(Q)$ gravitational theory are investigated, considering the charged scenario. Author's emphasis is on the power-law ansatz, which consistent with observations and is deemed the most viable. Because this solution does not have an uncharged version or relate to general relativity, it falls into a new category, which derives its features from changes in non-metricity and incorporates the Maxwell domain. The singularities of such a solution are analyzed, computing all the quantities of different curvature and non-metricity invariants. Author's results indicate the presence of a central singularity, albeit with a softer nature compared to standard non-metricity or Einstein general relativity, attributed to the influence of the effect of f ( Q ) $f(Q)$ . Several physical characteristics of black hole from thermodynamics perspective and demonstrate the existence of an outer event horizon in addition to the inner Cauchy horizons are examined. However, under the conditions of sufficiently large electric charge, a naked singularity emerges. Finally, a class of rotating black hole in four-dimensional f ( Q ) $f(Q)$ gravity that are asymptotically anti-de Sitter charged is derived.

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.
