摘要:

受约束微观模型的前景的启发,我们计算了精确的单圈校正de Sitter熵(球配分函数的对数)的每个有效场论的量子引力,与任意自旋表示的粒子。在这样做时,我们普遍地将球配分函数与准正则体和欧几里得边配分函数的商联系起来,该配分函数由编码可观测宇宙的体和边谱的字符的积分给出。扩展体特征将体(纠缠)熵分裂成准正规模(准量子比特)贡献。对于用sl($n$)Chern-Simons理论表示的三维高自旋引力,我们得到了全圈精确结果.此外,我们表明,该理论有一个指数大景观的德西特真空与量子熵的绝对值平方的拓扑弦配分函数。对于一般的高自旋引力,形式主义简洁地涉及dS,AdS $^\pm$和共形的结果。全息术表现在准精确体边缘抵消。

英文摘要:

Motivated by the prospect of constraining microscopic models, we calculate the exact one-loop corrected de Sitter entropy (the logarithm of the sphere partition function) for every effective field theory of quantum gravity, with particles in arbitrary spin representations. In doing so, we universally relate the sphere partition function to the quotient of a quasi-canonical bulk and a Euclidean edge partition function, given by integrals of characters encoding the bulk and edge spectrum of the observable universe. Expanding the bulk character splits the bulk (entanglement) entropy into quasinormal mode (quasiqubit) contributions. For 3D higher-spin gravity formulated as an sl($n$) Chern-Simons theory, we obtain all-loop exact results. Further to this, we show that the theory has an exponentially large landscape of de Sitter vacua with quantum entropy given by the absolute value squared of a topological string partition function. For generic higher-spin gravity, the formalism succinctly relates dS, AdS$^\pm$ and conformal results. Holography is exhibited in quasi-exact bulk-edge cancelation.
