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…
The JLMS formula in a large code with approximate error correction
Xi Dong, Donald Marolf, Pratik Rath
Gauge/gravity duality is often described as a quantum error correcting code. However, as seen in the Jafferis-Lewkowycz-Maldacena-Suh (JLMS) formula, exact quantum error correction…
Holographic codes and bulk RG flows
Xi Dong, Donald Marolf, Pratik Rath
We consider the coarse-graining of holographic quantum error correcting codes under a generalized notion of bulk renormalization-group flow. In particular, we study the renormaliza…
Constraints are not enough
Gary T. Horowitz, Donald Marolf, Jorge E. Santos
The Euclidean Einstein-Hilbert action is well-known to be unbounded below and thus to raise many questions regarding the definition of the gravitational path integral. A variety of…
Geometric Entropies and their Hamiltonian Flows
Xi Dong, Donald Marolf, Pratik Rath
In holographic theories, the Hubeny-Rangamani-Takayanagi (HRT) area operator plays a key role in our understanding of the emergence of semiclassical Einstein-Hilbert gravity. When…
