标题： Study of Information Restoring Effects in Virasoro Blocks

摘要： 众所周知，在大中心荷$c$极限下，CFT$_2$中的Virasoro块在研究对偶AdS$_3$理论中的BTZ黑洞时会遭受信息丢失。 最近的研究证明，非微扰$e^{-c}$修正可以解决信息丢失问题。 在这里，我们研究从有限$c$Virasoro共形块的一般性质中得出的重态谱的普遍特征。 此外，我们研究超越“Page”时间$ t \sim S_{BH}$的关联函数行为以及黑洞的熵。 在洛伦兹区域，我们希望更好地理解在重-轻极限下Virasoro块的指数衰减行为向晚期时间的幂律衰减的转变。 显示英文摘要

摘要： It is well-known that in the large central charge $c$ limit, the Virasoro blocks in CFT$_2$ suffer from information loss when studying the BTZ black holes in the dual AdS$_3$ theory. Recent studies have proved that non-perturbative $e^{-c}$ corrections resolves information loss. Here, we study universal features of the spectrum of heavy states from general properties of finite $c$ Virasoro conformal blocks. Furthermore, we investigate the behavior of correlators beyond "Page" time $ t \sim S_{BH}$, entropy of the black hole. In the Lorentzian regime, we wish to better understand the transition from an exponential decay behaviour of Virasoro blocks in the heavy-light limit to a power-law decay at late times.
