Quasinormal modes of warped $AdS_3$ black holes and AdS/CFT correspondence
Bin Chen, Zhi-bo Xu
TL;DR
This paper analytically computes scalar quasinormal modes of warped AdS3 black holes, revealing deviations from standard AdS/CFT predictions except near BTZ black holes where they remain consistent.
Contribution
It provides the first analytical calculation of quasinormal modes for warped AdS3 black holes and explores their relation to AdS/CFT correspondence.
Findings
Quasinormal modes generally do not match AdS/CFT predictions.
Near BTZ black holes, modes align with AdS/CFT expectations.
Analytical expressions for quasinormal frequencies are derived.
Abstract
We calculate the scalar quasinormal modes of warped black holes analytically. We find that in general they are not in agreement with the prediction of the usual AdS/CFT correspondence. Nevertheless, for the black hole not deviating far from BTZ black hole, the quasinormal frequencies are still well consistent with AdS/CFT correspondence.
