Abstract

This paper examines the thermodynamic properties and stability of deformed AdS-Schwarzschild black holes, focusing on the effects of deformation ( $α$ ) and thermal correction parameters ( $β_{1}$ , $β_{2}$ ) on phase transitions and heat capacity. The results show that higher $α$ values raise the Hawking-Page critical temperature, enhancing thermal stability. Thermal corrections significantly affect smaller black holes but minimally impact larger ones, leaving second-order phase transitions unchanged. Heat capacity analysis identifies stability regions, with sign changes marking instability. These findings highlight the role of deformation and thermal corrections in black hole stability, offering insights for extending our understanding of black hole thermodynamics.

热波动下变形ads -史瓦西黑洞的热力学

本文研究了变形ads -史瓦西黑洞的热力学性质和稳定性，重点研究了变形（α $\alpha$）和热校正参数(β 1 $\beta _1$，β 2 $\beta _2$)对相变和热容的影响。结果表明，α $\alpha$值越高，霍金-佩奇临界温度越高，热稳定性越好。热修正对较小的黑洞影响显著，但对较大的黑洞影响最小，使二阶相变保持不变。热容分析确定稳定区域，用符号变化表示不稳定。这些发现突出了变形和热修正在黑洞稳定性中的作用，为扩展我们对黑洞热力学的理解提供了见解。

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.
