Abstract

Recently, it has become increasingly clear that there are constraints on the low-energy effective theories of quantum gravity that cannot be captured by the standard Wilsonian paradigm. For gravitational theories in asymptotically anti-de Sitter spacetimes, we can formulate such constraints and aim to prove or falsify them using the AdS/CFT correspondence. I will review the work I did with Daniel Harlow on constraints on symmetries of quantum gravity. I will also discuss more recent progress in this holographic approach, and present the proof that Yifan Wang and I completed this year, which proves and strengthens a part of the Distance Conjecture that I proposed with Cumrun Vafa in 2006.

量子引力的约束

最近，越来越清楚的是，量子引力的低能量有效理论存在一些限制，这些限制不能被标准的威尔逊范式所捕获。对于渐近反德西特时空中的引力理论，我们可以制定这样的约束，并利用AdS/CFT对应来证明或证伪它们。我会回顾一下我和Daniel Harlow一起做的关于量子引力对称性约束的工作。我还将讨论这种全息方法的最新进展，并展示我和王一凡今年完成的证明，它证明并加强了我在2006年与Cumrun Vafa提出的距离猜想的一部分。

期刊介绍： General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
