Disentangling a Deep Learned Volume Formula
Jessica Craven, Vishnu Jejjala, Arjun Kar
We present a simple phenomenological formula which approximates the hyperbolic volume of a knot using only a single evaluation of its Jones polynomial at a root of unity. The avera…
Islands in de Sitter space
Vijay Balasubramanian, Arjun Kar, Tomonori Ugajin
We consider black holes in 2d de Sitter JT gravity coupled to a CFT, and entangled with matter in a disjoint non-gravitating universe. Tracing out the entangling matter leaves the…
Entanglement between two disjoint universes
Vijay Balasubramanian, Arjun Kar, Tomonori Ugajin
We use the replica method to compute the entanglement entropy of a universe without gravity entangled in a thermofield-double-like state with a disjoint gravitating universe. Inclu…
Spin structures and baby universes
Vijay Balasubramanian, Arjun Kar, Simon F. Ross +1
We extend a 2d topological model of the gravitational path integral to include sums over spin structure, corresponding to Neveu-Schwarz (NS) or Ramond (R) boundary conditions for f…
Geometric secret sharing in a model of Hawking radiation
Vijay Balasubramanian, Arjun Kar, Onkar Parrikar +2
We consider a black hole in three dimensional AdS space entangled with an auxiliary radiation system. We model the microstates of the black hole in terms of a field theory living o…
