论文摘要
我们提出了针对Jackiw-teitelboim重力的三维散装双重双重双重双重双重双重双重双重双重二维，并基于局部减少的CFT $ _2 $浴缸。散装双重双重的是经典的广告重力，缺陷brane在横向方向上有较小的波动。我们通过将横向波动视为DILATON场来得出完整的Jackiw-Teitelboim重力作用。我们证明，从岛公式计算出的细粒度熵与从极端表面计算出的粒子完全一致。我们的构造为Jackiw-Teitelboim重力提供了Lorentzian更高维的双重双重双重双重双重双重双重性，因此提供了一个框架来研究问题，例如黑洞信息悖论以及重力/集合二元性。
We propose the three-dimensional bulk dual for Jackiw-Teitelboim gravity coupled with CFT$_2$ bath based on partial reduction. The bulk dual is classical AdS gravity with a defect brane which has small fluctuation in transverse direction. We derive full Jackiw-Teitelboim gravity action by considering the transverse fluctuation as a dilaton field. We demonstrate that the fine grained entropy computed from island formula precisely agrees with that computed from defect extremal surface. Our construction provides a Lorentzian higher dimensional dual for Jackiw-Teitelboim gravity and therefore offers a framework to study problems such as black hole information paradox as well as gravity/ensemble duality.
