HAWKING RADIATION IN STRING THEORY AND THE STRING PHASE OF BLACK HOLES [PDF]

open access: green, 2000
The quantum string emission by Black Holes is computed in the framework of the `string analogue model' (or thermodynamical approach), which is well suited to combine QFT and string theory in curved backgrounds (particulary here, as black holes and ...

Non-Abelian black holes in string theory [PDF]

open access: yesJournal of High Energy Physics, 2017
We study a family of 5-dimensional non-Abelian black holes that can be obtained by adding an instanton field to the well-known D1D5W Abelian black holes. Naively, the non-Abelian fields seem to contribute to the black-hole entropy but not to the mass due

Weak gravity conjecture, black hole entropy, and modular invariance [PDF]

open access: yesJournal of High Energy Physics, 2019
In recent literature, it has been argued that a mild form of the Weak Gravity Conjecture (WGC) is satisfied by wide classes of effective field theories in which higher-derivative corrections can be shown to shift the charge-to-mass ratios of extremal ...

Microscopic formulation of black holes in string theory [PDF]

open access: green, 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.

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 ...

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.

The multipolar structure of fuzzballs

open access: yesJournal of High Energy Physics, 2021
We extend and refine a general method to extract the multipole moments of arbitrary stationary spacetimes and apply it to the study of a large family of regular horizonless solutions to N $$ \mathcal{N} $$ = 2 four-dimensional supergravity coupled to ...

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 ...

Quasinormal modes of stringy black holes [PDF]

open access: yes, 2001
String theory is a promising candidate for a fundamental quantum theory of all interactions including Einstein gravity. Some solutions in string theory can be interpreted as black holes. Using the semi-analytic method and WKB method,the quasinormal modes(

Two kissing bolts

open access: yesJournal 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 ...
