Strings and near-extremal black holes in theories with large superconformal symmetry
Sameer Murthy, Mukund Rangamani
We study the one-loop partition function of superstrings in the background. Specifically, we show that…
Thermal two-point functions in SYK and complex-time singularities
Ilija BuriÄ, Chi-Ming Chang, Ivan Gusev +3
We analyze the finite-temperature two-point function of the large- SYK model at intermediate couplings away from the infrared fixed point. Specifically, we examine its analytic…
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…
Looking at extremal black holes from very far away
Maciej Kolanowski, Donald Marolf, Ilija Rakic +2
Near-extremal black holes are subject to large quantum effects, which modify their low-temperature thermodynamic behavior. Hitherto, these quantum effects were analyzed by separati…
Strings in AdS: one-loop partition function and near-extremal BTZ thermodynamics
Christian Ferko, Sameer Murthy, Mukund Rangamani
We revisit the computation of the string partition function in AdS focussing on the appearance of spacetime (super) symmetries. We show how the asymptotic symmetries of the AdS…
