complexity corresponding to deformations of the bath state by a relevant scalar operator …

Holographic thermal correlators from supersymmetric instantons

M Dodelson, A Grassi, C Iossa, DP Lichtig… - SciPost Physics, 2023 - scipost.org
We present an exact formula for the thermal scalar two-point function in four-dimensional
holographic conformal field theories. The problem of finding it reduces to the analysis of the …

Trans-IR flows to black hole singularities

E Caceres, A Kundu, AK Patra, S Shashi - Physical Review D, 2022 - APS
We study analytic continuations of holographic renormalization group (RG) flows beyond
their infrared (IR) fixed points. Such “trans-IR” flows are a natural framework for describing …

Kasner eons with matter: holographic excursions to the black hole singularity

E Cáceres, ÁJ Murcia, AK Patra, JF Pedraza - Journal of High Energy …, 2024 - Springer
A bstract Recent work has shown that introducing higher-curvature terms to the Einstein-
Hilbert action causes the approach to a space-like singularity to unfold as a sequence of …
