本研究在共形Weyl引力框架下探究原始彭罗斯过程（PP）及黑洞（BH）热力学。该理论有量纲常数γ与κ，其中γ编码渐近平直时空中星系旋转曲线的渐近旋转曲率，κ与宇宙学背景常数Λ相关。我们确定该理论中旋转黑洞的事件视界位置与极端构型，给出事件视界半径的微扰及精确表达式。测地线方程被限制在赤道平面内，仅在该平面内研究包括能量提取过程在内的对应动力学。主要结果为：检验原始彭罗斯过程的可行性与效率，分析黑洞减速机制，验证共形Weyl引力框架下黑洞热力学四定律的有效性。
英文摘要
This work investigates the original Penrose process (PP), as well as black hole (BH) thermodynamics, within the framework of conformal Weyl gravity. The theory is characterized by the dimensionful constants $γ$, which encodes the asymptotic rotational curvature of galactic rotation curves in an otherwise asymptotically flat spacetime, and $κ$, which is associated with the cosmological background constant $Λ$. We determine the locations of the event horizon and the extreme configurations for rotating BHs in this theory, and we provide both perturbative and exact expressions for the event horizon radius. The geodesic equations are restricted to the equatorial plane, and the corresponding dynamics, including energy extraction processes, are studied exclusively in this plane. As the principal results, we examine the feasibility and efficiency of the original PP, analyze BH deceleration mechanisms, and test the validity of the four laws of BH thermodynamics in the context of conformal Weyl gravity.
