(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 ...

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.

Dynamically and thermodynamically stable black holes in Einstein-Maxwell-dilaton gravity

open access: yesJournal of High Energy Physics, 2020
We consider Einstein-Maxwell-dilaton gravity with the non-minimal exponential coupling between the dilaton and the Maxwell field emerging from low energy heterotic string theory.

Black holes and solitons in string theory [PDF]

open access: yesPhysics 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.

Notes on islands in asymptotically flat 2d dilaton black holes

open access: yesJournal 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.

Black holes at accelerators [PDF]

open access: yes, 2010
In theories with large extra dimensions and TeV-scale gravity, black holes are copiously produced in particle collisions at energies well above the Planck scale.

Ultra-spinning Chow’s black holes in six-dimensional gauged supergravity and their properties

open access: yesJournal of High Energy Physics, 2021
By taking the ultra-spinning limit as a simple solution-generating trick, a novel class of ultra-spinning charged black hole solutions has been constructed from Chow’s rotating charged black hole with two equal-charge parameters in six-dimensional N ...

Microscopic Calabi-Yau Black Holes in String Theory [PDF]

open access: yes, 2011
In this thesis we study microscopic aspects of Calabi-Yau black holes in string theory. We compute the absorption cross-section of the space-time massless scalars by the world-volume of D2-branes, wrapped on the S2 of an AdS_2 x S^2 x CY_3 geometry of a ...

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

open access: yesPhysical 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.
