Abstract

In this paper, we investigate the thermodynamic properties and emission energy of Anti-de-Sitter (AdS) black holes within the framework of Kalb-Ramond gravity. By analyzing the modified Einstein equations with the inclusion of the antisymmetric Kalb-Ramond tensor field, we explore the changes in key thermodynamic quantities such as temperature, entropy, and specific heat, alongside the emission energy spectrum associated with Hawking radiation. The study reveals novel thermal behaviors and energy emission patterns compared to standard AdS black holes, particularly highlighting the influence of the Kalb-Ramond field on black hole stability and phase transitions. Furthermore, we examine the role of the Kalb-Ramond field in modifying the emission energy. Our findings provide deeper insights into black hole thermodynamics, the emission process, and the broader role of antisymmetric fields in gravitational physics. Different paths for test particles near black holes are determined by their distance from the innermost stable circular orbit, which plays a crucial role in this study. The unique behavior of particles impacted by mass and rotational momentum is highlighted by the fact that particles within the innermost stable circular orbits tend to converge toward the singularity, but particles outside tend to diverge toward infinity.
卡尔布-拉蒙特引力中反-德西特黑洞的热化学现象
在本文中,我们在卡尔布-拉蒙特引力的框架内研究了反德西特(AdS)黑洞的热力学性质和发射能量。通过分析包含反对称卡尔布-拉蒙特张量场的修正爱因斯坦方程,我们探索了温度、熵和比热等关键热力学量的变化,以及与霍金辐射相关的发射能谱。与标准 AdS 黑洞相比,这项研究揭示了新颖的热行为和能量辐射模式,尤其突出了卡尔布-拉蒙德张量场对黑洞稳定性和相变的影响。此外,我们还研究了卡尔布-拉蒙德场在改变发射能量方面的作用。我们的发现为黑洞热力学、发射过程以及反对称场在引力物理学中的广泛作用提供了更深入的见解。测试粒子在黑洞附近的不同路径是由它们与最内层稳定圆形轨道的距离决定的,这在本研究中起着至关重要的作用。受质量和旋转动量影响的粒子的独特行为突出表现在:在最内层稳定圆形轨道内的粒子趋向于向奇点汇聚,而在轨道外的粒子则趋向于向无穷发散。

期刊介绍: The journal welcomes manuscripts on theoretical models, simulations, and observations of highly energetic astrophysical objects both in our Galaxy and beyond. Among those, black holes at all scales, neutron stars, pulsars and their nebula, binaries, novae and supernovae, their remnants, active galaxies, and clusters are just a few examples. The journal will consider research across the whole electromagnetic spectrum, as well as research using various messengers, such as gravitational waves or neutrinos. Effects of high-energy phenomena on cosmology and star-formation, results from dedicated surveys expanding the knowledge of extreme environments, and astrophysical implications of dark matter are also welcomed topics.
