Title: Holography and Entanglement in Flat Spacetime

Speaker: Dr. Li Wei

University of Tokyo

Abstract:We propose a holographic correspondence of the flat spacetime based on the behavior of the entanglement entropy and the

correlation functions. The holographic dual theory turns out to be highly non-local. We argue that after most part of the space is traced

out, the reduced density matrix gives the maximal entropy and the correlation functions become trivial. We present a toy model for this

holographic dual using a non-local scalar field theory that reproduces the same property of the entanglement entropy. Our conjecture is

consistent with the entropy of Schwarzschild black holes in asymptotically flat spacetimes.
