Effects of Noncommutativity on the Black Hole Entropy

The BTZ black hole geometry is probed with a noncommutative scalar field which obeys the κ-Minkowski algebra. The entropy of the BTZ black hole is calculated using the brick wall method. The

Higher order WKB corrections to black hole entropy in brick wall formalism

We calculate the statistical entropy of a quantum field with an arbitrary spin propagating on the spherical symmetric black hole background by using the brick wall formalism at higher orders in the

Entropy of three-dimensional BTZ black holes

The entropies of scalar field and neutrino field are calculated in the back-ground of three-dimensional BTZ black hole. Considering statistical physics, we propose not to consider the superraradiant

Entropy and black hole horizons

Aspects of black hole quantum mechanics and thermodynamics in 2+1 dimensions.

It is shown that the dynamical variables of the black hole arise from the possibility of a deficit angle at the (Euclidean) horizon, and briefly speculate as to how they may provide a basis for a statistical picture of black hole thermodynamics.

It is shown that the entropy of the (2+1)-dimensional black hole can be obtained as the logarithm of the number of microscopic states, leading to the appearance of new physical states at the horizon.

This entropy is shown to satisfy an increase theorem on either the global or apparent horizon of a two-dimensional black hole.

Black hole in three-dimensional spacetime.

The standard Einstein-Maxwell equations in 2+1 spacetime dimensions, with a negative cosmological constant, admit a black hole solution that appears as a negative energy state separated by a mass gap from the continuous black hole spectrum.

The entropy per unit area is shown to be finite to all orders in superstring perturbation theory, and the importance of these conclusions to the resolution of the problem of black hole information loss is reiterated.

Temperature, energy, and heat capacity of asymptotically anti-de Sitter black holes.

The thermodynamic properties of black holes in (3+1)- and (2+1-dimensional Einstein gravity with a negative cosmological constant are investigated and it is shown that the chemical potential conjugate to angular momentum is equal to the proper angular velocity of the black hole with respect to observers who are at rest in the stationary time slices.

End point of Hawking radiation.

The formation and semi-classical evaporation of two-dimensional black holes is studied in an exactly solvable model where infalling matter is reflected from a time-like naked singularity and all information is recovered at spatial infinity.
