چکیده
We introduce an analog model for the conformally coupled scalar field on BTZ black hole. The is based propagation of acoustic waves in a Laval nozzle. Since hole not globally hyperbolic spacetime, dynamics well defined until extra boundary conditions are prescribed at its spatial infinity. show that quasinormal modes (QNMs) satisfying Dirichlet, Neumann, and Robin can be interpreted terms ordinary QNMs with respect to appropriately extended also discuss stability our small perturbations.

Bulk and Boundary Dynamics in BTZ Black Holes
Recently, the AdS/CFT conjecture of Maldacena has been investigated in Lorentzian signature by Balasubramanian et. al. We extend this investigation to Lorentzian BTZ black hole spacetimes, and study the bulk and boundary behaviour of massive scalar fields both in the non-extremal and extremal case. Using the bulk-boundary correspondence, we also evaluate the two-point correlator of operators co...
متن کاملRotating BTZ Black Holes
We have considered the divergence structure in the brick-wall model for the statistical mechanical entropy of a quantum field in thermal equilibrium with a black hole which rotates. Especially, the contribution to entropy from superradiant modes is carefully incorporated, leading to a result for this contribution which corrects some previous errors in the literature. It turns out that the previ...
متن کاملStrings in extremal BTZ black holes
We study the spectrum of the worldsheet theory of the bosonic closed string in the massless and extremal rotating BTZ black holes. We use a hyperbolic Wakimoto representation of the SL(2,R) currents to construct vertex operators for the string modes on these backgrounds. We argue that there are tachyons in the twisted sector, but these are not localised near the horizon. We study the relation t...
متن کاملMassless BTZ black holes in minisuperspace
We study aspects of the propagation of strings on BTZ black holes. After performing a careful analysis of the global spacetime structure of generic BTZ black holes, and its relation to the geometry of the SL(2, R) group manifold, we focus on the simplest case of the massless BTZ black hole. We study the SL(2, R) Wess-Zumino-Witten model in the worldsheet minisuperspace limit, taking into accoun...
متن کاملUnitarity issue in BTZ black holes
We study the wave equation for a massive scalar in three-dimensional AdS-black hole spacetimes to understand the unitarity issues in a semiclassical way. Here we introduce four interesting spacetimes: the non-rotating BTZ black hole (NBTZ), pure AdS spacetime (PADS), massless BTZ black hole (MBTZ), and extremal BTZ black hole (EBTZ). Our method is based on the potential analysis and solving the...
