摘要:

本文证明人工智能可以通过自主解决理论物理中的一个开放问题来加速数学发现。我们提出了一种混合系统,结合Gemini Deep Think大型语言模型和系统化的树搜索(TS)框架以及自动数值反馈,成功推导出宇宙弦发射的引力辐射功率谱的新、精确的解析解。具体来说,该代理评估了任意环形几何的核积分I(N,α),直接改进了最近的AI辅助尝试[BCE+25],后者仅得到了部分渐近解。为了验证我们关于AI加速发现的方法论主张并确保透明度,我们详细说明了系统提示、搜索约束以及间歇性反馈循环,这些指导了模型。代理识别出一套6种不同的解析方法,其中最优雅的一种将核在Gegenbauer多项式C_l^(3/2)中展开,自然吸收积分的奇点。这些方法导致了I(N,α)在大N处的渐近结果,既与数值结果一致,也与量子场论的连续费曼参数化相连接。我们详细说明了使这一发现成为可能的算法方法以及由此产生的数学推导。

英文摘要:

This paper demonstrates that artificial intelligence can accelerate mathematical discovery by autonomously solving an open problem in theoretical physics. We present a neuro-symbolic system, combining the Gemini Deep Think large language model with a systematic Tree Search (TS) framework and automated numerical feedback, that successfully derived novel, exact analytical solutions for the power spectrum of gravitational radiation emitted by cosmic strings. Specifically, the agent evaluated the core integral $I(N,α)$ for arbitrary loop geometries, directly improving upon recent AI-assisted attempts \cite{BCE+25} that only yielded partial asymptotic solutions. To substantiate our methodological claims regarding AI-accelerated discovery and to ensure transparency, we detail system prompts, search constraints, and intermittent feedback loops that guided the model. The agent identified a suite of 6 different analytical methods, the most elegant of which expands the kernel in Gegenbauer polynomials $C_l^{(3/2)}$ to naturally absorb the integrand's singularities. The methods lead to an asymptotic result for $I(N,α)$ at large $N$ that both agrees with numerical results and also connects to the continuous Feynman parameterization of Quantum Field Theory. We detail both the algorithmic methodology that enabled this discovery and the resulting mathematical derivations.
