During the last twenty-five years evidence has been mounting that a black-hole surface area has a discrete spectrum. Moreover, it is widely believed that area eigenvalues are uniformly spaced. There is, however, no general agreement on the spacing of the levels. In this Letter we use Bohr's correspondence principle to provide this missing link. We conclude that the area spacing of a black hole is $4\ensuremath{\Elzxh}\mathrm{ln}3$. This is the unique spacing consistent both with the area… Expand

Area Spectrum of Black Holes with Quantum Corrections via Periodicity
• Physics
• 2014
Using the Heisenberg uncertainty principle, Bekenstein once claimed that the horizon area of a black hole is quantized with uniform spacing $8\pi l_{p}^{2}$. This spacing is shown to be correctedExpand
On the Kerr quantum area spectrum
Suppose that there is a quantum operator that describes the horizon area of a black hole. Then what would be the form of the ensuing quantum spectrum? In this regard, it has been conjectured that theExpand
Universal area spectrum in single-horizon black holes
• Physics
• 2004
We investigate highly damped quasinormal mode of single-horizon black holes motivated by its relation to the loop quantum gravity. Using the WKB approximation, we show that the real part of theExpand

Abstract The entropy-area spectrum of a black hole has been a long-standing and unsolved problem. Based on a recent methodology introduced by two of the authors, for the black hole radiation (HawkingExpand
Periodicity and area spectrum of the three dimensional BTZ black hole
• Physics
• 2012
Very recently, a new scheme to quantize the horizon area of a black hole has been proposed by Zeng and Liu et al. In this paper, we further apply the analysis to investigate area spectrum of threeExpand
Quantization of Horizon Area from the NUT-Kerr-Newman Black Hole
The aim of this Letter is to investigate the spectroscopy of the NUT-Kerr-Newman black hole by improving the method of revisited adiabatic invariant quantity. We present the modified expression ofExpand
Comparison of area spectra in loop quantum gravity
• Physics

The entropy-area spectrum of a black hole has been a long-standing and unsolved problem. Based on a recent methodology introduced by two of the authors, for the black hole radiation (Hawking effect)Expand
ON THE "UNIVERSAL" QUANTUM AREA SPECTRUM
There has been much debate about the form of the quantum area spectrum for a black hole horizon, with the evenly spaced conception of Bekenstein having featured prominently in the discourse. Here, weExpand
Discrete quantum spectrum of black holes

Abstract The quantum genesis of Hawking radiation is a long-standing puzzle in black hole physics. Semi-classically one can argue that the spectrum of radiation emitted by a black hole look very muchExpand
