On Non-Critical Superstring/Black Hole Transition [PDF]
Phys.Rev.D73:086008,2006, 2005 An interesting case of string/black hole transition occurs in two-dimensional non-critical string theory dressed with a compact CFT. In these models the high energy densities of states of perturbative strings and black holes have the same leading behavior when the Hawking temperature of the black hole is equal to the Hagedorn temperature of ...

Towards a Full Quantum Theory of Black Holes [PDF]
, 1998 This review gives an introduction to various attempts to understand the quantum nature of black holes. The first part focuses on thermodynamics of black holes, Hawking radiation, and the interpretation of entropy.

Black holes and solitons in string theory [PDF]
Physics Reports, 1999 We review various aspects of classical solutions in string theories. Emphasis is placed on their supersymmetry properties, their special roles in string dualities and microscopic interpretations. Topics include black hole solutions in string theories on tori and N=2 supergravity theories; p-branes; microscopic interpretation of black hole entropy.

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 ...

Notes on islands in asymptotically flat 2d dilaton black holes
Journal of High Energy Physics, 2020 We study the islands and the Page curve in the 1+1-dimensional eternal dilaton black hole models. Without islands, the entanglement entropy of the radiation grows linearly at late time.

Three-Charge Black Holes and Quarter BPS States in Little String Theory [PDF]
, 2015 We show that the system of $k$ NS5-branes wrapping $\mathbb{T}^4\times S^1$ has non-trivial vacuum structure. Different vacua have different spectra of 1/4 BPS states that carry momentum and winding around the $S^1$.

Black holes in string theory with duality twists [PDF]
Journal of High Energy Physics, 2020 Abstract We consider 5D supersymmetric black holes in string theory compactifications that partially break supersymmetry. We compactify type IIB on T4 and then further compactify on a circle with a duality twist to give Minkowski vacua preserving partial supersymmetry ($$ \mathcal{N} $$ N = 6, 4 ...

Journal of High Energy Physics, 2018 Using the blackfold effective theory applied to extremal Kerr branes we provide evidence for the existence of new stationary extremal black hole solutions in asymptotically flat spacetime with both single and multiple disconnected horizons. These include

Gravitational footprints of black holes and their microstate geometries
Journal of High Energy Physics, 2021 We construct a family of non-supersymmetric extremal black holes and their horizonless microstate geometries in four dimensions. The black holes can have finite angular momentum and an arbitrary charge-to-mass ratio, unlike their supersymmetric cousins ...

On the black hole interior in string theory [PDF]
Journal of High Energy Physics, 2017 The potential behind the horizon of an eternal black hole in classical theories is described in terms of data that is available to an external observer -- the reflection coefficient of a wave that scatters on the black hole. In GR and perturbative string theory (in $ '$), the potential is regular at the horizon and it blows up at the singularity.
