String scale black holes at large D

open access: yesJournal of High Energy Physics, 2022
We study aspects of black holes near the Hagedorn temperature. The large dimension expansion introduced by Soda, Emparan, Grumiller and Tanabe connects them to the well studied two dimensional black hole based on SL(2) k /U(1).

State-Space Geometry, Statistical Fluctuations, and Black Holes in String Theory [PDF]

open access: yesAdvances in High Energy Physics, 2014
We study the state-space geometry of various extremal and nonextremal black holes in string theory. From the notion of the intrinsic geometry, we offer a state-space perspective to the black hole vacuum fluctuations.

On black holes in string theory [PDF]

open access: yes, 2011
PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

A stringy effect on Hawking radiation

open access: yesJournal of High Energy Physics, 2023
In string theories, interactions are exponentially suppressed for trans-Planckian space-like external momenta. We study a class of quantum field theories that exhibit this feature modeled after Witten’s bosonic open string field theory, and discover a ...

Spontaneous scalarization in (A)dS gravity at zero temperature

open access: yesJournal of High Energy Physics, 2022
We study spontaneous scalarization of electrically charged extremal black holes in D ≥ 4 spacetime dimensions. Such a phenomenon is caused by the symmetry breaking due to quartic interactions of the scalar — Higgs potential and Stueckelberg interaction ...

Cosmic necklaces in string theory and field theory [PDF]

open access: yes, 2010
PhDIn this thesis we investigate astrophysical phenomena which arise in models with compact extra dimensions, focussing on the cosmological consequences of strings which wrap cycles in the internal space. Embedding our strings in the Klebanov-Strassler

An entropy current for dynamical black holes in four-derivative theories of gravity

open access: yesJournal of High Energy Physics, 2020
We propose an entropy current for dynamical black holes in a theory with arbitrary four derivative corrections to Einstein’s gravity, linearized around a stationary black hole.

Islands in Schwarzschild black holes

open access: yesJournal of High Energy Physics, 2020
We study the Page curve for asymptotically flat eternal Schwarzschild black holes in four and higher spacetime dimensions. Before the Page time, the entanglement entropy grows linearly in time.

(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.
