Mass spectrum and statistical entropy of the BTZ black hole from canonical quantum gravity
Abstract
In a recent publication we developed a canonical quantization program describing the gravitational collapse of a spherical dust cloud in 2+1 dimensions with a negative cosmological constant {lambda}{identical_to}l{sup 2}<0. In this paper we address the quantization of the BanadosTeitelboimZanelli (BTZ) black hole. We show that the mass function describing the black hole is made of two pieces, a constant nonvanishing boundary contribution and a discrete spectrum of the form {mu}{sub n}=(({Dirac_h}/2{pi})/l)(n+(1/2)). The discrete spectrum is obtained by applying the WheelerDeWitt equation with a particular choice of factor ordering and interpreted as giving the energy levels of the collapsed matter shells that form the black hole. Treating a black hole microstate as a particular distribution of shells among the levels, we determine the canonical entropy of the BTZ black hole. Comparison with the BekensteinHawking entropy shows that the boundary energy is related to the central charge of the Virasoro algebra that generates the asymptotic symmetry group of the threedimensional antide Sitter space AdS{sub 3}. This gives a connection between the WheelerDeWitt approach and the conformal field theory approach.
