Evaporation of microscopic black holes in string theory and the bound on species [PDF]

, 2009
We address the question how string compactifications with D‐branes are consistent with the black hole bound, which arises in any theory with number of particle species to which the black holes can evaporate.

Entropy of three-dimensional black holes in string theory [PDF]

, 1998
It is observed that the three-dimensional BTZ black hole is a supersymmetric solution of the low-energy field equations of heterotic string theory compactified on an Einstein space. The solution involves a non-zero dilaton and NS-NS H-field.

Habemus superstratum! A constructive proof of the existence of superstrata [PDF]

, 2015
We construct the first example of a superstratum: a class of smooth horizonless supergravity solutions that are parameterized by arbitrary continuous functions of (at least) two variables and have the same charges as the supersymmetric D1-D5-P black hole.

Exact holography and black hole entropy in N=8 and N=4 string theory [PDF]

, 2017
We compute the exact entropy of one-eighth and one-quarter BPS black holes in N=8 and N=4 string theory respectively. This includes all the N=4 CHL models in both K3 and T^4 compactifications.

Two kissing bolts

Journal of High Energy Physics, 2018
The study of non-supersymmetric black hole microstates offers the potential to resolve the black hole information paradox. A system of equations was recently obtained that enables the systematic construction of non-supersymmetric smooth horizonless ...

String theory and the principle of black hole complementarity [PDF]

Physical Review Letters, 1993
String theory provides an example of the kind of apparent inconsistency that the {\it Principle of Black Hole Complementarity\/} deals with. To a freely infalling observer a string falling through a black hole horizon appears to be a Planck size object.

A stringy glimpse into the black hole horizon

Journal of High Energy Physics, 2018
We elaborate on the recent claim [1] that non-perturbative effects in α′, which are at the core of the FZZ duality, render the region just behind the horizon of the SL(2, ℝ) k /U(1) black hole singular already at the classical level (g s = 0).

Null geodesics of charged black holes in string theory [PDF]

, 2011
In this paper, we investigate the null geodesics of the static charged black hole in heterotic string theory. A detailed analysis of the geodesics are done in the Einstein frame as well as in the string frame.

Stability of charged black holes in string theory under charged massive scalar perturbations [PDF]

, 2013
Similar to the superradiant effect in Reissner-Nordstr\"{o}m black hole, a charged scalar field can be amplified when impinging on the charged black hole in string theory. According to the black-hole bomb mechanism,the mass term of the incident field can
