New Black Hole Solutions in f(P) Gravity and their Thermodynamic Nature

Aniruddha Ghosh, Ujjal Debnath

AI总结:

本文在f(P)引力中构建了首个静态球对称黑洞解(史瓦西解的推广),解析计算其热力学量并发现小视界半径下的热力学稳定性,为引力理论与黑洞热力学研究提供新案例。

摘要:

黑洞是宇宙中极具吸引力的天体,代表着时空几何的极端形变。本文构建了f(P)引力,并给出了f(P)引力中静态球对称黑洞解的首个例子,同时讨论了其热力学性质。通过数值方法和级数解,我们得到了该解并证明它是史瓦西解的推广。该解由一个满足非线性四阶微分方程的单函数表征。有趣的是,我们能解析计算出该解的比热、Wald熵和霍金温度作为视界半径的函数。对比热分析后发现,该黑洞在小视界半径范围内具有热力学稳定性。

英文摘要:

Black holes are the fascinating objects in the universe. They represent extreme deformations in spacetime geometry. Here, we construct f(P) gravity and the first example of static-spherically symmetric black hole solution in f(P) gravity and discuss their thermodynamics. Using the numerical approach and series solution, we discover the solution and demonstrate that it is a generalization of Schwarzschild. The solution is characterized by a single function that satisfies a nonlinear fourth order differential equation. Interestingly, we can analytically calculate the solution s specific heat, Wald entropy, and Hawking temperature as a function of horizon radius. After analyzing the specific heat, we discovered that the black hole is thermodynamically stable over a small horizon radius.
