摘要:

一个从引力宇宙的体相中提取物理的具体模型,对于研究量子引力及其与实验之间可能存在的联系非常重要。在 AdS/CFT 对应中,可以通过在体反德西特(AdS)时空的渐近边界上粘合一个热库来构造这样的模型。该热库模拟实验室,并由一个量子场论描述。在对偶共形场论(CFT)描述中,这种耦合通过将 CFT 与热库耦合的双迹形变实现。这表明实验室所观测到的物理是完全幺正的。本文中,我们详细分析了该模型的量子层面,由此带来关于 AdS/CFT 对应的新认识,并讨论了该模型在理解引力宇宙中子区域物理方面的潜在用途。

英文摘要:

A concrete model of extracting the physics from the bulk of a gravitational universe is important to the study of quantum gravity and its possible relationship with experiments. Such a model can be constructed in the AdS/CFT correspondence by gluing a bath on the asymptotic boundary of the bulk anti-de Sitter (AdS) spacetime. This bath models a laboratory and is described by a quantum field theory. In the dual conformal field theory (CFT) description this coupling is achieved by a double-trace deformation that couples the CFT with the bath. This suggests that the physics observed by the laboratory is fully unitary. In this paper, we analyze the quantum aspects of this model in detail which conveys new lessons about the AdS/CFT correspondence, and we discuss the potential usefulness of this model in understanding subregion physics in a gravitational universe.
