Study of Information Restoring Effects in Virasoro Blocks
arXiv:2409.13766
Abstract
It is well-known that in the large central charge limit, the Virasoro blocks in CFT suffer from information loss when studying the BTZ black holes in the dual AdS theory. Recent studies have proved that non-perturbative corrections resolves information loss. Here, we study universal features of the spectrum of heavy states from general properties of finite Virasoro conformal blocks. Furthermore, we investigate the behavior of correlators beyond "Page" time , 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.
