本文提出一种解析求解器，通过度量重构在宇称偶三次引力中构建首个线性阶旋转黑洞度量，并严格验证场方程，为超越爱因斯坦引力的强场测试奠定基础。
AI 中文摘要
我们将度量重构转化为修正引力中旋转黑洞的解析求解器，绕过了耦合场方程的直接求解。作为示例，在宇称偶三次引力中，我们构建了在耦合线性阶上的首个解析旋转黑洞度量，无需自旋或弱场展开。我们严格验证了场方程，并重现了关于视界性质的独立解析预测。这为构建爱因斯坦引力之外的旋转黑洞开辟了新途径，并为强场测试奠定了基础。
英文摘要
We turn metric reconstruction into an analytic solver for rotating black holes in modified gravity, bypassing the direct solution of coupled field equations. As an example, in parity-even cubic gravity, we construct the first analytic spinning black hole metric at linear order in the coupling, without spin or weak-field expansions. We stringently validate the field equations and reproduce independent analytic predictions for horizon properties. This establishes a new route to construct spinning black holes beyond Einstein gravity and lays the foundation for strong-field tests.
