De Sitter Bra-Ket Wormholes
Alessandro Fumagalli, Victor Gorbenko, Joshua Kames-King
We study a model for the initial state of the universe based on a gravitational path integral that includes connected geometries which simultaneously produce bra and ket of the wav…
Ensemble Averages of Orbifold Classes of Narain CFTs
Stefan Forste, Hans Jockers, Joshua Kames-King +2
In this work we study families of orbifolds of toroidal conformal field theories based on both factorizable and non-factorizable target space tori. For these classes…
The Lion, the Witch, and the Wormhole: Ensemble averaging the symmetric product orbifold
Joshua Kames-King, Alexandros Kanargias, Bob Knighton +1
We consider the ensemble average of two dimensional symmetric product orbifold CFTs over the Narain moduli space. We argue for a bulk dual given by …
Complexity via Replica Trick
Mohsen Alishahiha, Souvik Banerjee, Joshua Kames-King
We consider the complexity of a single-sided AdS black hole as modelled by an end-of-the-world brane. In addition, we present multi-boundary partition functions and matter correlat…
No Page Curves for the de Sitter Horizon
Joshua Kames-King, Evita Verheijden, Erik Verlinde
We investigate the fine-grained entropy of the de Sitter cosmological horizon. Starting from three-dimensional pure de Sitter space, we consider a partial reduction approach, which…
Deformations of JT Gravity via Topological Gravity and Applications
Stefan Forste, Hans Jockers, Joshua Kames-King +1
We study the duality between JT gravity and the double-scaled matrix model including their respective deformations. For these deformed theories we relate the thermal partition func…
Complexity as a holographic probe of strong cosmic censorship
Mohsen Alishahiha, Souvik Banerjee, Joshua Kames-King +1
Based on reasonable assumptions, we propose a new expression for Lloyd's bound, which confines the complexity growth of charged black holes. We then revisit holographic complexity…
Supersymmetric Black Holes and the SJT/nSCFT Correspondence
Stefan Forste, Andreas Gerhardus, Joshua Kames-King
We consider 1/4 BPS black hole solutions of gauged supergravity in . The near horizon geometry is and supersymmetry is enhanced. In the first…
Towards the Holographic Dual of N = 2 SYK
Stefan Forste, Joshua Kames-King, Max Wiesner
The gravitational part of the holographic dual to the SYK model has been conjectured to be Jackiw-Teitelboim (JT) gravity. In this paper we construct an AdS2 background in N = (2,2…
