Connections between entropy surface density and microscopic property in black holes [PDF]
arXiv, 2021 We introduce a new microscopic quantity $\varepsilon $ that describes the contribution of a single black hole molecule to black hole entropy and give a key relation that this microscopic quantity is proportional to the macroscopic quantity -- entropy surface density $\sigma_{S}$, thus connecting a microscopic quantity to a macroscopic quantity of black

Tidal forces in dirty black hole spacetimes
European Physical Journal C: Particles and Fields, 2022 Black holes can be inserted in very rich astrophysical environments, such as accretion disks. Although isolated black holes are simple objects in general relativity, their accretion disks may significantly enrich the field configurations of their ...

Journal of High Energy Physics, 2014 We study six-dimensional rotating black holes with bumpy horizons: these are topologically spherical, but the sizes of symmetric cycles on the horizon vary non-monotonically with the polar angle. We construct them numerically for the first three bumpy families, and follow them in solution space until they approach critical solutions with localized ...

Properties of rotating Einstein-Maxwell-Dilaton black holes in odd dimensions
, 2013 We investigate rotating Einstein-Maxwell-Dilaton (EMd) black holes in odd dimensions. Focusing on black holes with equal-magnitude angular momenta, we determine the domain of existence of these black holes.

Phases of Higher Dimensional Black Holes [PDF]
Mod.Phys.Lett.A23:2625-2643,2008, 2008 We review some of the most striking properties of the phase diagrams of higher dimensional black holes in pure gravity. We focus on static black hole solutions with Kaluza-Klein asymptotics and stationary black hole solutions in flat Minkowski space.

Do stringy corrections stabilize coloured black holes? [PDF]
, 1999 We consider hairy black hole solutions of Einstein-Yang-Mills-Dilaton theory, coupled to a Gauss-Bonnet curvature term, and we study their stability under small, spacetime-dependent perturbations. We demonstrate that the stringy corrections do not remove

Macroscopic Black Holes, Microscopic Black Holes and Noncommutative Membrane
, 2003 We study the stretched membrane of a black hole as consisting of a perfect fluid. We find that the pressure of this fluid is negative and the specific heat is negative too.

Many accelerating black holes [PDF]
, 2001 We show how the Weyl formalism allows metrics to be written down which correspond to arbitrary numbers of collinear accelerating neutral black holes in 3+1 dimensions.
