Comment on "Black hole constraints on varying fundamental constants"

open access: yes, 2008
In the Letter [1] (also [2]) there is a claim that the generalised second law of thermodynamics (entropy increase) for black holes provides some limits on the rate of variation of the fundamental constants of nature (electric charge e, speed of light c ...

Is the Rindler horizon energy nonvanishing ?

open access: yes, 2006
A nonvanishing value for the Rindler horizon energy is proposed, by an analogy with the "near horizon" Schwarzschild metric. We show that the Rindler horizon energy is given by the same formula $E = \alpha/2$ obtained by Padmanabhan for the Schwarzschild

Comments on "Entropy of 2D Black Holes from Counting Microstates"

open access: yes, 1999
In a recent letter, Cadoni and Mignemi proposed a formulation for the statistical computation of the 2D black holes entropy.

Classical Electron Model with QED Corrections [PDF]

open access: yes, 2010
In this article we build a metric for a classical general relativistic electron model with QED corrections. We calculate the stress-energy tensor for the radiative corrections to the Coulomb potential in both the near-field and far-field approximations ...

Static black holes in equilibrium with matter: nonlinear equation of state

open access: yes, 2010
We consider a spherically symmetric black hole in equilibrium with surrounding classical matter that is characterized by a nonlinear dependence of the radial pressure p_{r} on the density {\rho}. We examine under which requirements such an equilibrium is

Black hole remnants due to GUP or quantum gravity?

open access: yes, 2005
Based on the micro-black hole \emph{gedanken} experiment as well as on general considerations of quantum mechanics and gravity the generalized uncertainty principle (GUP) is analyzed by using the running Newton constant.

Addentum to: Conformal Invariance and Near-extreme Rotating AdS Black Holes

open access: yes, 2014
We obtained retarded Green's functions for massless scalar fields in the background of near-extreme, near-horizon rotating charged black hole of five-dimensional minimal gauged supergravity in Phys. Rev. D84, 044018 (2011).

The Central Charge of the Warped AdS^3 Black Hole

open access: yes, 2010
The AdS/CFT conjecture offers the possibility of a quantum description for a black hole in terms of a CFT. This has led to the study of general AdS^3 type black holes with a view to constructing an explicit toy quantum black hole model.

Information geometry of asymptotically AdS black holes

open access: yes, 2009
We investigate thermodynamic geometries of two families of asymptotically Anti-de Sitter black holes, i.e. the Reissner-Nordstr\"om Anti-de Sitter in four dimensions and the BTZ black hole.

Quantum entropy of two-dimensional extreme charged dilaton black hole

open access: yes, 1998
By using Hawking's treatment as well as Zaslavskii's treatment respectively and the brick wall model, two different values of classical entropy and quantum entropy of scalar fields in the two-dimensional extreme charged dilaton black hole backgrounds ...
