Exact holographic thermal spectral functions: OPE, non-perturbative corrections, and black hole singularity
Hewei Frederic Jia, Mukund Rangamani
We study analytic properties of thermal spectral functions of holographic CFTs, examining both their (a) exact properties at finite momentum and (b) asymptotics at large momentum.…
Thermal spectral function asymptotics and black hole singularity in holography
Hewei Frederic Jia, Mukund Rangamani
We investigate the analytic structure of thermal spectral function of holographic CFTs, synthesizing recent developments into a set of observations about its asymptotics. Specifica…
Holographic thermal correlators and quasinormal modes from semiclassical Virasoro blocks
Hewei Frederic Jia, Mukund Rangamani
Motivated by its relevance for thermal correlators in strongly coupled holographic CFTs, we refine and further develop a recent exact analytic approach to black hole perturbation p…
Twist operator correlators and isomonodromic tau functions from modular Hamiltonians
Hewei Frederic Jia
We introduce a novel approach for computing the twist operator correlators (TOC) in two-dimensional conformal field theories (2d CFT) and the closely related isomonodromic tau func…
Twist operator correlator revisited and tau function on Hurwitz space
Hewei Frederic Jia
Correlation function of twist operators is a natural quantity of interest in two-dimensional conformal field theory (2d CFT) and finds relevance in various physical contexts. For c…
Petz reconstruction in random tensor networks
Hewei Frederic Jia, Mukund Rangamani
We illustrate the ideas of bulk reconstruction in the context of random tensor network toy models of holography. Specifically, we demonstrate how the Petz reconstruction map works…
