AI 中文摘要
在广义相对论中,加速黑洞由C-度规描述。我们研究该几何如何被高导数修正所改变,重点关注宇称为偶数和奇数的三次曲率项。利用合适的度规拟设,我们在耦合常数的一阶获得了闭式解。修正后的几何包含新的积分常数,这些常数对应于C-度规的物理形变,并且根据修正的宇称表现出不同的行为。特别是,宇称破坏项会产生非对角度规分量并诱导旋转。对于AdS解,我们分析了热力学,包括霍金温度、熵和弦张力,并讨论了定义质量和热力学弦长度时的微妙之处。
英文摘要
Accelerating black holes in General Relativity are described by the C-metric. We study how this geometry is modified by higher-derivative corrections, focusing on cubic curvature terms of even and odd parity. Using a suitable metric ansatz, we obtain closed-form solutions at first order in the coupling constants. The corrected geometries contain new integration constants, which correspond to physical deformations of the C-metric, and exhibit different behavior depending on the parity of the correction. In particular, parity-violating terms generate an off-diagonal metric component and induce rotation. For AdS solutions, we analyze the thermodynamics, including the Hawking temperature, entropy, and string tensions, and discuss the subtleties in defining the mass and thermodynamic string lengths.
