论文摘要
信息损失悖论的最引人注目的证据之一是，根据霍金的计算，测试标量场的相关函数会及时衰减。在本文中，我认为在经典马鞍点上明智地使用了最陡峭的下降扩张（黑洞背景），足以将早期衰减变为较晚的时间，与信息检索一致。我将在Jackiw-teitelboim重力中明确显示这一点。在那里，在散装tow点函数中所谓的“坡道”是在分析中获得的，而无需重力路径积分的任何其他亚辅助配置。
One of the most striking evidences of the information loss paradox is that, according to the Hawking's calculation, the correlation functions of a test scalar field exponentially decay in time. In this paper, I argue that a judicious use of the steepest descent expansion on the classical saddle point (the Black Hole background), is enough to change this early time decay into a late time growing, in agreement with information retrieval. I will explicitly show this in the Jackiw-Teitelboim gravity. There, the so-called "ramp" in the bulk tow-point function, is analytically obtained without the need of any other subdominant configurations of the gravity path integral.
