Wormholes as red herrings: reflection positivity and the reconstruction of unitary quantum field theories
Jacob McNamara, Zhencheng Wang
As Coleman famously argued, the apparent breakdown of partition-function factorization in quantum gravity associated with Euclidean wormholes is a red herring, arising from a hidde…
Lorentzian Path Integrals and Jackiw-Teitelboim wormholes with imaginary scalars
Jesse Held, Molly Kaplan, Donald Marolf +1
The Lorentzian path integral was recently used to argue that standard Euclidean axion wormholes do not dominate computations of connected AdS/CFT partition functions. We now apply…
Axion Wormholes and the AdS/CFT Factorization Problem
Jesse Held, Molly Kaplan, Donald Marolf +1
This work investigates the relevance of Euclidean and complex axion wormholes to the AdS/CFT factorization problem. We use a framework that defines bulk gravitational path integral…
Gravitational Algebras with Two Areas
Xuchen Cao, Thomas Faulkner, Zhencheng Wang
We study gravitational algebras on spacetimes with two extremal surfaces. In the example of a long wormhole with two asymptotic AdS boundaries and two compact extremal surfaces, we…
Wormholes with Ends of the World
Diandian Wang, Zhencheng Wang, Zixia Wei
We study classical wormhole solutions in 3D gravity with end-of-the-world (EOW) branes, conical defects, kinks, and punctures. These solutions compute statistical averages of an en…
Euclidean and complex geometries from real-time computations of gravitational Rényi entropies
Jesse Held, Xiaoyi Liu, Donald Marolf +1
Gravitational Rényi computations have traditionally been described in the language of Euclidean path integrals. In the semiclassical limit, such calculations are governed by Eucli…
