Quantization of black hole entropy from quasinormal modes
Using the new physical interpretation of quasinormal modes proposed by Maggiore, we calculate the quantum spectra of entropy for various types of non-rotating black holes with no charge. The spectrum

Entropy of higher dimensional nonrotating isolated horizons from loop quantum gravity
In this paper, we extend the calculation of the entropy of nonrotating isolated horizons in four-dimensional spacetime to that in a higher-dimensional spacetime. We show that the boundary degrees of
Reformulation of boundary BF theory approach to statistical explanation of the entropy of isolated horizons
It is shown in this paper that the symplectic form for the system consisting of D-dimensional bulk Palatini gravity and SO(1, 1) BF theory on an isolated horizon as a boundary just contains the bulk
On the black hole singularity issue in loop quantum gravity
This paper presents a brief overview on the issue of singularity resolution in loop quantum gravity presented at the Theory CANADA IV conference at the Centre de Recherches Mathematiques at the
Entropy quantization of Reissner-Nordström de Sitter black hole via adiabatic covariant action
Based on the ideas of adiabatic invariant quantity, we attempt to quantize the entropy of a charged black hole in de Sitter spacetime in two different coordinates. The entropy spectrum is obtained by
Volume entropy
Building on a technical result by Brunnemann and Rideout on the spectrum of the Volume operator in Loop Quantum Gravity, we show that the dimension of the space of the quadrivalent, diffeomorphism
Remarks on Spectroscopy via Adiabatic Invariance from the Kerr Black Hole
By imposing Bohn-Sommerfeld quantization rule and the laws of black hole thermodynamics to the modified adiabatic covariant action, the spectroscopy of the Kerr black hole is obtained in different
Entropy in spin foam models: the statistical calculation
Recently an idea for computing the entropy of black holes in the spin foam formalism has been introduced. Particularly complete calculations for the three-dimensional Euclidean BTZ black hole were
Anisotropic Structures and Wormholes with Loop Quantum Gravity Holonomy Corrections
Anisotropic spherically symmetric systems are studied in the connection and densitized triad variables used in loop quantum gravity. The material source is an anisotropic fluid, which is arguably the

This work argues that for a (macroscopically) Schwarzschild black hole this ensemble is formed by horizons with the same area, and obtains a statistical entropy proportional to the area, as in the Bekenstein-Hawking formula.
Quasinormal modes, the area spectrum, and black hole entropy.
A result from classical gravity concerning the quasinormal mode spectrum of a black hole is used to fix the Immirzi parameter and the Bekenstein-Hawking expression of A/4l(2)(P) for the entropy of ablack hole is arrived at.

Loop Quantum Gravity and Black Hole Physics
I summarize the basic ideas and formalism of loop quantum gravity. I illustrate the results on the discrete aspects of quantum geometry and two applications of these results to black hole physics. In
Quantum geometry of isolated horizons and black hole entropy
Using the earlier developed classical Hamiltonian framework as the point of departure, we carry out a non-perturbative quantization of the sector of general relativity, coupled to matter, admitting
The complete spectrum of the area from recoupling theory in loop quantum gravity
We compute the complete spectrum of the area operator in the loop representation of quantum gravity, using recoupling theory. This result extends previous derivations, which did not include the
Linking topological quantum field theory and nonperturbative quantum gravity
Quantum gravity is studied nonperturbatively in the case in which space has a boundary with finite area. A natural set of boundary conditions is studied in the Euclidean signature theory in which the
Quantum geometry and black hole entropy
A ``black hole sector'' of nonperturbative canonical quantum gravity is introduced. The quantum black hole degrees of freedom are shown to be described by a Chern-Simons field theory on the horizon.
From qubits to black holes: Entropy, entanglement and all that
Entropy plays a crucial role in the characterization of information and entanglement, but it is not a scalar quantity and for many systems it is different for different relativistic observers. We
