Ahmed Almheiri (NYU Abu Dhabi) “Spacetime discreteness and its IR effects”

Seminar Organizer

Event Details

Abstract: The idea that spacetime may be discrete in the UV, possibly at the Planck scale, has been fraught with issues due to generically strong effects of such discreteness on the flow of a quantum field theory down to the IR. Nevertheless, recent work on two dimensional models of holography seem to provide an example of the emergence of spacetime from a discrete lattice-like structure. In this talk, I will provide an overview of these and discuss how the holographic models evade some of the issues of previous attempts at discretizing spacetime. Work (very much) in progress.
