Mass Quantization of the Schwarzschild Black Hole
نویسنده
چکیده
We examine the Wheeler-DeWitt equaton for a static, eternal Schwarzschild black hole in Kuchař-Brown variables and obtain its energy eigenstates. Consistent solutions vanish in the exterior of the Kruskal manifold and are non-vanishing only in the interior. The system is reminiscent of a particle in a box. States of definite parity avoid the singular geometry by vanishing at the origin. These definite parity states admit a discrete energy spectrum, depending on one quantum number which determines the Arnowitt-Deser-Misner (ADM) mass of the black hole according to a relation conjectured long ago by Bekenstein, M ∼ nMp. If attention is restricted only to these quantized energy states, a black hole is described not only by its mass but also by its parity. States of indefinite parity do not admit a quantized 1 Email: [email protected] 2 On leave of absence from the Universidade do Algarve, Faro, Portugal 3 Email: [email protected]

Canonical Quantization and the Statistical Entropy of the Schwarzschild Black Hole
The canonical quantization of a Schwarzschild black hole yields a picture of the black hole that is shown to be equivalent to a collection of oscillators whose density of levels is commensurate with that of the statistical bootstrap model. Energy eigenstates of definite parity exhibit the Bekenstein mass spectrum, M ∼ √ NMp, where N ∈ N. From the microcanonical ensemble, we derive the statistic...
متن کاملNear Extremal Schwarzschild-de Sitter Black Hole Area Spectrum from Quasi-normal Modes
Using the quasi-normal modes frequency of near extremal Schwarzschild-de Sitter black holes, we obtain area and entropy spectrum for black hole horizon. By using Boher-Sommerfeld quantization for an adiabatic invariant I = ∫ dE ω(E) , which E is the energy of system and ω(E) is vibrational frequency, we leads to an equally spaced mass spectrum. In the other term we extend directly the Kunstatte...
متن کاملQuasinormal Modes, Reduced Phase Space and Area Spectrum of Black Holes
Motivated by the recent interest in quantization of black hole area spectrum, we consider the area spectrum of Schwarzschild, BTZ, extremal Reissner-Nordström, near extremal Schwarzschild-de Sitter, and Kerr black holes. Based on the proposal by Bekenstein and others that the black hole area spectrum is discrete and equally spaced, we implement Kunstatter's method to derive the area spectrum fo...
متن کاملQuantization of a Phase Space S 1 × R + and the Mass Spectrum of Schwarzschild Black Holes in D Space - Time Dimensions
The symplectic reduction of pure spherically symmetric (Schwarzschild) classical gravity in D space-time dimensions yields a 2-dimensional phase space of obser-vables consisting of the mass M (> 0) and a canonically conjugate (Killing) time variable T. Imposing (mass-dependent) periodic boundary conditions in time on the associated quantum mechanical plane waves which represent the Schwarzschil...
متن کاملSchrödinger Equation of the Schwarzschild Black Hole Jarmo
We describe the gravitational degrees of freedom of the Schwarzschild black hole by one free variable. We introduce an equation which we suggest to be the Schrödinger equation of the Schwarzschild black hole corresponding to this model. We solve the Schrödinger equation explicitly and obtain the mass spectrum of the black hole as such as it can be observed by an observer very far away and at re...
