Emergent classical spacetime from microstates of an incipient black hole
Vijay Balasubramanian, David Berenstein, Aitor Lewkowycz +3
Black holes have an enormous underlying space of microstates, but universal macroscopic physics characterized by mass, charge and angular momentum as well as a causally disconnecte…
Code subspaces for LLM geometries
David Berenstein, Alexandra Miller
We consider effective field theory around classical background geometries with a gauge theory dual, in the class of LLM geometries. These are dual to half-BPS states of …
Superposition induced topology changes in quantum gravity
David Berenstein, Alexandra Miller
We show that superpositions of classical states in quantum gravity with fixed topology can lead to new classical states with a different topology. We study this phenomenon in a par…
Logarithmic enhancements in conformal perturbation theory and their real time interpretation
David Berenstein, Alexandra Miller
We study various corrections of correlation functions to leading order in conformal perturbation theory, both on the cylinder and on the plane. Many problems on the cylinder are ma…
Topology and geometry cannot be measured by an operator measurement in quantum gravity
David Berenstein, Alexandra Miller
In the context of LLM geometries, we show that superpositions of classical coherent states of trivial topology can give rise to new classical limits where the topology of spacetime…
Reconstructing spacetime from the hologram, even in the classical limit, requires physics beyond the Planck scale
David Berenstein, Alexandra Miller
We argue in this essay that for classical configurations of gravity in the AdS/CFT setup, it is in general impossible to reconstruct the bulk geometry from the leading asymptotic b…
Conformal perturbation theory, dimensional regularization and AdS/CFT
David Berenstein, Alexandra Miller
We study relevant deformations of conformal field theory on a cylinder using conformal perturbation theory, and in particular the one point function of the deformation operator and…
