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…

Looking at bulk points in general geometries
Simon Caron-Huot, Joydeep Chakravarty, Keivan Namjou
The holographic correspondence predicts that certain strongly coupled quantum systems describe an emergent, higher-dimensional bulk spacetime in which excitations enjoy local dynam…

Boundary imprint of bulk causality
Simon Caron-Huot, Joydeep Chakravarty, Keivan Namjou
Motivated by the holographic correspondence, we study the boundary imprint of bulk lightcones in spacetimes with boundaries. These lightcones can be observed whenever a localized e…
