Price's law from quasinormal modes
Paolo Arnaudo, Benjamin Withers
We show that Price's power-law tail for perturbations of Schwarzschild, as , can be obtained from a sum of Schwarzschild-de Sitter quasinormal modes in…
Beyond quasinormal modes: a complete mode decomposition of black hole perturbations
Paolo Arnaudo, Javier Carballo, Benjamin Withers
We show that retarded Green's functions of black hole spacetimes can be expressed as a convergent mode sum everywhere in spacetime. At late times a quasinormal mode sum converges,…
One loop corrections to the thermodynamics of near-extremal Kerr-(A)dS black holes from Heun equation
Paolo Arnaudo, Giulio Bonelli, Alessandro Tanzini
We compute one-loop corrections to the euclidean gravitational path integral of near-extremal (anti-)de Sitter-Kerr black hole in terms of the connection coefficients of the Heun e…
QNM orthogonality relations for AdS black holes
Paolo Arnaudo, Javier Carballo, Benjamin Withers
We present orthogonality relations for quasinormal modes of a wide class of asymptotically AdS black holes. The definition is obtained from a standard product, modified by a CPT op…
One-loop corrections to near extremal Kerr thermodynamics from semiclassical Virasoro blocks
Paolo Arnaudo, Giulio Bonelli, Alessandro Tanzini
We propose a method to perform an exact calculation of one-loop quantum corrections to black hole entropy in terms of Virasoro semiclassical blocks. We analyse in detail four-dimen…
Exact low-temperature Green's functions in AdS/CFT: From Heun to confluent Heun
Paolo Arnaudo, Benjamin Withers
We obtain exact expressions for correlation functions of charged scalar operators at finite density and low temperature in CFT dual to the RN-AdS black brane. We use recent…
