ABSTRACT
In this Letter, we show that Jackiw-Teitelboim gravity can be naturally realized in the Karch-Randall braneworld. Notably the role of the dilaton in Jackiw-Teitelboim gravity is played by the radion in a suitably orbifolded version of the setup. In the classical entanglement entropy calculation, there is an apparent degeneracy of Ryu-Takayanagi surfaces. We demonstrate how quantum fluctuations of the radion/dilaton resolve this would-be classical puzzle regarding entanglement wedge reconstruction.
