AI总结:

本文提出通过Born-Oppenheimer约简将渐近量子引力的红外部分描述为几何理论,其中量子化作为全局一致性条件出现。

摘要:

我们通过外部观察者可访问的渐近配置来表征渐近平坦量子引力的红外部分。从Regge-Teitelboim哈密顿量出发,该哈密顿量在存在引力约束的情况下生成物理演化,我们对其进行Born-Oppenheimer约简,将缓慢渐近数据与快速本体引力波动分离。我们证明,消去快速部分会在渐近电荷空间上诱导一个功能 Berry 连接,因此有效的红外动力学由该电荷空间上的平行运输支配。在该框架下,红外引力态自然组织成由诱导连接的holonomy标记的超选择sector,且在追踪掉紫外本体模式后获得的约化密度矩阵获得几何贡献。这提供了渐近量子引力部分的有效几何描述,其中量子化作为亚迪亚运输下的全局一致性条件出现,而非局部本体算符的谱性质。

英文摘要:

We formulate the infrared sector of asymptotically flat quantum gravity in terms of asymptotic configurations accessible to external observers. Starting from the Regge-Teitelboim Hamiltonian that generates physical evolution in the presence of gravitational constraints, we perform a Born-Oppenheimer reduction separating slow asymptotic data from fast bulk gravitational fluctuations. We show that integrating out the fast sector induces a functional Berry connection over the space of asymptotic charges, so that the effective infrared dynamics is governed by parallel transport on this charge space. In this framework, infrared gravitational states are naturally organized into superselection sectors labelled by the holonomy of the induced connection, and the reduced density matrix obtained after tracing over ultraviolet bulk modes acquires a geometric contribution. This provides an effective geometric description of the asymptotic quantum gravitational sector, where quantization arises as a global consistency condition under adiabatic transport rather than as a spectral property of local bulk operators.
