In this review, we summarize exact results for the three-dimensional BTZ black hole. We use rigorous mathematical results to clarify the general structure and properties of this black hole spacetime and its microscopic description. In particular, we study the formation of the black hole by point particle collisions, leading to an exact analytic determination of the Choptuik scaling parameter. W...

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...

We consider the duality of the quasilocal black hole thermodynamics, explicitly the quasilocal black hole thermodynamic first law, in BTZ black hole solution as a special one of the three-dimensional low energy effective string theory.

We search for all Poisson brackets for the BTZ black hole which are consistent with the geometry of the commutative solution and are of lowest order in the embedding coordinates. For arbitrary values for the angular momentum we obtain two two-parameter families of contact structures. We obtain the symplectic leaves, which characterize the irreducible representations of the noncommutative theory...

A recent paper [M. Kamata and T. Koikawa, Phys. Lett. B353 (1995) 196.] claimed to obtain the charged version of the (2 + 1)-dimensional spinning BTZ black hole solution by assuming a (anti-) self dual condition imposed on the electric and magnetic fields. We point out that the angular momentum and mass diverge at spatial infinity and as a consequence the solution is unphysical

We calculate the quasinormal modes and associated frequencies of the Bañados, Zanelli and Teitelboim (BTZ) non-rotating black hole. This black hole lives in 2+1-dimensions in an asymptotically anti-de Sitter spacetime. We obtain exact results for the wavefunction and quasi normal frequencies of scalar, electromagnetic and Weyl (neutrino) perturbations. E-mail: [email protected] E-mail:...

We study linear scalar perturbations of black holes in two-dimensional (2D) gravity models with a particular emphasis on Jackiw-Teitelboim (JT) gravity. obtain an exact expression the quasinormal mode frequencies for single horizon JT and then verify it numerically using Horowitz-Hubeny method. For 2D Reissner-Nordstr\"om like solution, we find that massless wave equation reduces to confluent H...

Herein, we extend Joule-Thomson expansion to the low-dimensional regime by considering rotating Ba\~nados-Teitelboim-Zanelli (BTZ) metric in ($2+1$)-dimensional space-time. Specifically, properties of three important aspects expansion, including coefficient, inversion curve, and isenthalpic curve were studied. The divergence point coefficient zero Hawking temperature investigated. curves $T--P$...

A bstract We compute the quasi-normal frequencies of scalars in asymptotically-flat microstate geometries that have same charge as a D1-D5-P black hole, but whose long BTZ-like throat ends smooth cap. In general wave equation is not separable, we find class which non-separable term negligible and can using WKB methods. argue our results are universal property all with deeply-capped BTZ throats....
