Rotating Kaluza–Klein black holes [PDF]

open access: yesNuclear Physics B, 2000
All regular four-dimensional black holes are constructed in the theory obtained by Kaluza-Klein reduction of five-dimensional Einstein gravity. They are interpreted in string theory as rotating bound states of D0- and D6-branes. Conservation of angular momentum is important for the stability of the bound states.

Non-uniqueness, Counterrotation, and Negative Horizon Mass of Einstein-Maxwell-Chern-Simons Black Holes [PDF]

open access: yes, 2006
Stationary black holes in 5-dimensional Einstein-Maxwell-Chern-Simons theory possess surprising properties. When considering the Chern-Simons coefficient $\lambda$ as a parameter, two critical values of $\lambda$ appear: the supergravity value $\lambda_{\

Universal thermodynamic topological classes of rotating black holes

open access: yesPhysics Letters B
In a recent study, Wei et al. (2024) [96] proposed a universal classification scheme that interprets black hole solutions, including the four-dimensional Schwarzschild, Reissner-Nordström (RN), Schwarzschild-AdS, and RN-AdS black hole solutions, as ...

From rotating to charged black holes and back again

open access: yesJournal of High Energy Physics, 2022
The mild form of the Weak Gravity Conjecture (WGC) requires higher derivative corrections to extremal charged black holes to increase their charge-to-mass ratio. This allows decay via emission of a smaller extremal black hole.

Thermodynamic Curvature of AdS Black Holes with Dark Energy

open access: yesFrontiers in Physics, 2021
In this paper, we study the effect of dark energy on the extended thermodynamic structure and interacting microstructures of black holes in AdS, through an analysis of thermodynamic geometry.

The Evolution of Distorted Rotating Black Holes III: Initial Data [PDF]

open access: yes, 1996
In this paper we study a new family of black hole initial data sets corresponding to distorted ``Kerr'' black holes with moderate rotation parameters, and distorted Schwarzschild black holes with even- and odd-parity radiation.

Quest for realistic non-singular black-hole geometries: regular-center type

open access: yesJournal of High Energy Physics, 2022
We propose seven criteria to single out physically reasonable non-singular black-hole models and adopt them to four different spherically symmetric models with a regular center and their rotating counterparts. In general relativity, all such non-singular

Non-asymptotically flat, non-AdS dilaton black holes

open access: yes, 2004
We show that previously known non-asymptotically flat static black hole solutions of Einstein-Maxwell-dilaton theory may be obtained as near-horizon limits of asymptotically flat black holes.

Chaos and rotating black holes with halos [PDF]

open access: yesPhysical Review D, 1997
The occurrence of chaos for test particles moving around a slowly rotating black hole with a dipolar halo is studied using Poincaré sections. We find a novel effect, particles with angular momentum opposite to the black hole rotation have larger chaotic regions in phase space than particles initially moving in the same direction.
