Entanglement tsunami in ( 1 + 1 )-dimensions

Year: 2015

Type: article

Abstract: We study the time dependence of the entanglement entropy of disjoint intervals following a global quantum quench in ($1+1$)-dimensional CFTs at large $c$ with a sparse spectrum. The result agrees with a holographic calculation but differs from the free field theory answer. In particular, a simple model of free quasiparticle propagation is not adequate for CFTs with a holographic dual. We elaborate on the entanglement tsunami proposal of Liu and Suh and show how it can be used to reproduce the holographic answer.
