Fast scrambling as Brownian motion in a fluid with negative viscosity (1704.04444v1)
Published 13 Apr 2017 in gr-qc and hep-th
Abstract: It is shown that the fast scrambling of information in a black hole can be viewed as Brownian motion of information in a fluid with negative viscosity (and negative temperature). It is argued that a non-local character of the fast scrambling is only an illusion; the stretched horizon with negative viscosity is an amplifying medium that mimics non-locality and superluminal communication.
