Quantum Solitons
Robie A. Hennigar, Ayan K. Patra, Simon F. Ross
We construct geometries describing the quantum backreaction of thermal fields in AdS. The solutions are obtained from branes in a four-dimensional AdS C-metric. They can be vie…
The spectrum of pure dS gravity in the static patch
Joydeep Chakravarty, Alexander Maloney, Keivan Namjou +1
We consider the quantum mechanical description of the de Sitter static patch in three-dimensional general relativity. We consider a Lorentzian path integral that conjecturally comp…
Cosmology inside a black hole: adding matter on the brane
José L. F. Barbón, Ayan K. Patra, Juan F. Pedraza +1
Braneworlds inside an AdS black hole provide simple models where a closed cosmology can be encoded in a dual field theory. Previous studies have focused on pure-tension branes, whe…
A new observable for holographic cosmology
Joydeep Chakravarty, Alexander Maloney, Keivan Namjou +1
The double-cone geometry is a saddle of the gravitational path integral, which explains the chaotic statistics of the spectrum of black hole microstates. This geometry is the usual…
