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…

Transient dynamics of quasinormal mode sums
Javier Carballo, Benjamin Withers
Quasinormal modes of spacetimes with event horizons are typically governed by a non-normal operator. This gives rise to spectral instabilities, a topic of recent interest in the bl…
