3D Einstein action from 6D Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +1
In view of embedding 3D gravity into topological string theory, we show that the dimensional reduction of 6D Kodaira-Spencer gravity on , i.e. the low-energ…
Complexity and the Hilbert space dimension of 3D gravity
Vijay Balasubramanian, Rathindra Nath Das, Johanna Erdmenger +2
A central problem in formulating a theory of quantum gravity is to determine the size and structure of the Hilbert space of black holes. Here we use a quantum dynamical Krylov comp…
Topological Einstein gravity as Kodaira-Spencer gravity
Johanna Erdmenger, Jonathan Karl, Jani Kastikainen +2
As a contribution towards quantizing three-dimensional gravity, we show at the classical level that Euclidean three-dimensional Einstein gravity with a negative cosmological consta…
Non-Locality induces Isometry and Factorisation in Holography
Souvik Banerjee, Johanna Erdmenger, Jonathan Karl
In holography, two manifestations of the black hole information paradox are given by the non-isometric nature of the bulk-boundary map and by the factorisation puzzle. By consideri…
Discrete JT gravity as an Ising model
Johanna Erdmenger, Jonathan Karl, Yanick Thurn +2
Inspired by the program of discrete holography, we show that Jackiw-Teitelboim (JT) gravity on a hyperbolic tiling of Euclidean AdS gives rise to an Ising model on the dual lat…
Towards Explicit Discrete Holography: Aperiodic Spin Chains from Hyperbolic Tilings
Pablo Basteiro, Giuseppe Di Giulio, Johanna Erdmenger +3
We propose a new example of discrete holography that provides a new step towards establishing the AdS/CFT duality for discrete spaces. A class of boundary Hamiltonians is obtained…
