Microstates of a 2d Black Hole in string theory

open access: yesJournal of High Energy Physics, 2023
Abstract We analyse models of Matrix Quantum Mechanics in the double scaling limit that contain non-singlet states. The finite temperature partition function of such systems contains non-trivial winding modes (vortices) and is expressed in terms of a group theoretic sum over representations. We then focus in the case when the first

Microscopic formulation of black holes in string theory [PDF]

open access: yes, 2002
In this report we review the microscopic formulation of the five-dimensional black hole of type IIB string theory in terms of the D1–D5 brane system. The emphasis here is more on the brane dynamics than on supergravity solutions.

STRING THEORY ON THREE-DIMENSIONAL BLACK HOLES [PDF]

open access: yesInternational Journal of Modern Physics A, 1998
We investigate the string theory on three-dimensional black holes discovered by Bañados, Teitelboim and Zanelli in the framework of conformal field theory. The model is described by an orbifold of the [Formula: see text] WZW model. The spectrum is analyzed by solving the level matching condition and we obtain winding modes.

Stationary charged scalar clouds around black holes in string theory [PDF]

open access: yes, 2016
It was reported that Kerr-Newman black holes can support linear charged scalar fields in their exterior regions. These stationary massive charged scalar fields can form bound states, which are called stationary scalar clouds.

Black holes in supergravity and string theory [PDF]

open access: yesClassical and Quantum Gravity, 2000
We give an elementary introduction to black holes in supergravity and string theory. The focus is on BPS solutions in four- and higher-dimensional supergravity and string theory. Basic ideas and techniques are explained in detail, including exercises with solutions.

Aspects of Topological String Theory [PDF]

open access: yes, 2008
Two aspects of the topological string and its applications are considered in this thesis. Firstly, non-perturbative contributions to the OSV conjecture relating four-dimensional extremal black holes and the closed topological string partition function ...

(Non-adiabatic) string creation on nice slices in Schwarzschild black holes

open access: yesJournal of High Energy Physics, 2017
Nice slices have played a pivotal role in the discussion of the black hole information paradox as they avoid regions of strong spacetime curvature and yet smoothly cut through the infalling matter and the outgoing Hawking radiation, thus, justifying the ...

On the nonexistence of a vacuum black lens

open access: yesJournal of High Energy Physics, 2021
We demonstrate that five-dimensional, asymptotically flat, stationary and bi-axisymmetric, vacuum black holes with lens space L(n, 1) topology, possessing the simplest rod structure, do not exist.

General rotating black holes in string theory: Greybody factors and event horizons [PDF]

open access: yes, 1997
We derive the wave equation for a minimally coupled scalar field in the background of a general rotating five-dimensional black hole. It is written in a form that involves two types of thermodynamic variables, defined at the inner and outer event horizon,

Extremal black holes, Stueckelberg scalars and phase transitions

open access: yesJournal of High Energy Physics, 2018
We calculate the entropy of a static extremal black hole in 4D gravity, non-linearly coupled to a massive Stueckelberg scalar. We find that the scalar field does not allow the black hole to be magnetically charged.
