标题： Jackiw-Teitelboim Gravity from the Karch-Randall Braneworld

摘要： 在本文中，我们表明杰克维-泰特尔博姆（JT）引力可以在卡奇-兰道布膜世界中自然实现。值得注意的是，JT引力中的标量场角色由适当轨道化版本设置中的径向场所扮演。在经典纠缠熵计算中，存在Ryu-Takayanagi表面的明显简并。我们展示了径向场/标量场的量子涨落如何解决关于纠缠楔重建的潜在经典谜题。 显示英文摘要

摘要： 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.
