论文摘要
在这封信中，我们表明jackiw-teitelboim（JT）重力可以在Karch-Randall Braneworld中自然实现。值得注意的是，DILATON在JT重力中的作用是在适当的Orbifold版本的设置中扮演的。在经典的纠缠熵计算中，ryu-takayanagi表面有明显的变性。我们证明了辐射/dilaton的量子波动如何解决这一可能的古典难题，这些难题是关于纠缠楔的重建。
In this letter, we show that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld. Notably the role of the dilaton in JT 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 resolves this would-be classical puzzle regarding entanglement wedge reconstruction.
