Entanglement entropy in Jackiw-Teitelboim Gravity

High Energy Physics - Theory 2018-08-21 v3

Abstract

I show that the black hole entropy associated to an AdS2AdS_2 wormhole is an entanglement edge term related to a natural measure on the gauge group in the SL(2)SL(2) gauge theory formulation of 1+1d1+1d Jackiw-Teitelboim gravity. I comment on what the entropy appears to be counting.
