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…
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…
Liouville theory and the Weil-Petersson geometry of moduli space: bordered, conic, and higher genus surfaces
Kale Colville, Sarah M. Harrison, Alexander Maloney +1
Two-dimensional conformal field theory is a powerful tool to understand the geometry of surfaces. Here, we study Liouville conformal field theory in the classical (large central ch…
