Retrieving black hole information from the main Lorentzian saddle point

C Germani - Physical Review D, 2022 - APS
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 …

Aspects of deformed 2D topological gravity : from partition function to late-time SFF

A Bhattacharyya, S Ghosh, S Pal - arXiv preprint arXiv:2309.16658, 2023 - arxiv.org
In this paper, we investigate different thermodynamic properties of $ T\bar {T}+ J\bar {T} $
deformed 2D-gravity. First, we compute the partition function of $ U (1) $ coupled 2D-gravity …
