Black hole collisions, instabilities, and cosmic censorship violation at large D

open access: yesJournal of High Energy Physics, 2019
We study the evolution of black hole collisions and ultraspinning black hole instabilities in higher dimensions. These processes can be efficiently solved numerically in an effective theory in the limit of large number of dimensions D.

Scrambling‐Enhanced Quantum Battery Charging in Black Hole Analogues

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
By employing a black‐hole‐analog quantum battery constructed from a position‐dependent XY model, its dynamical behavior is investigated through a quench of the scrambling parameter. It is systematically quantified that how the simulated scrambling improves key performance metrics‐namely, stored energy, peak power, and charging time‐thereby offering a ...

Quantum smearing of spacetime singularity [PDF]

open access: yesClassical and Quantum Gravity, 1995
The author proposes a quantum mechanical generalization of the affine length of a curve. An application is given in the \((2+ 1)\)-dimensional black hole model.

The Analysis of Singular Spacetimes [PDF]

open access: yesPhilosophy of Science, 1999
Much controversy surrounds the question of what ought to be the proper definition of ‘singularity’ in general relativity, and the question of whether the prediction of such entities leads to a crisis for the theory. I argue that a definition in terms of curve incompleteness is adequate, and in particular that the idea that singularities correspond to ...

End of the world brane networks for infinite distance limits in CY moduli space

open access: yesJournal of High Energy Physics
Dynamical Cobordism provides a powerful method to probe infinite distance limits in moduli/field spaces parameterized by scalars constrained by generic potentials, employing configurations of codimension-1 end of the world (ETW) branes.

Stringy effects and the role of the singularity in holographic complexity

open access: yesJournal of High Energy Physics, 2019
There has been considerable recent interest in holographic complexity. The two leading conjectures on this subject hold that the quantum complexity of the boundary thermofield double state should be dual to either the volume of the Einstein-Rosen bridge ...

Directional Quantum Singularities in Curzon Spacetime

open access: yesUniverse
The scalar quantum probe method developed by Horowitz and Marolf is applied to the cylindrically symmetric Curzon solution. The main cause for choosing the Curzon solution is that it is the best-known example that exhibits directional singularity ...

A Primer on Spacetime Singularities I: Mathematical Framework

open access: yesUniverse
This article presents a comprehensive and rigorous overview of spacetime singularities within the framework of classical General Relativity. Singularities are defined through the failure of geodesic completeness, reflecting the limits of predictability ...

On some universal features of the holographic quantum complexity of bulk singularities

open access: yesJournal of High Energy Physics, 2018
We perform a comparative study of the time dependence of the holographic quantum complexity of some space like singular bulk gravitational backgrounds.

Spacetime singularities and indeterminism

open access: yesSynthese
Abstract We argue for the claim that spacetime singularities in general relativity (GR) signal indeterminism, broadly construed. We first develop a schema for diagnosing a type of indeterminism for physical theories, which we denote by Indeterminism.
